It reminds me of the Slotin Incident (http://www.damninteresting.com/bitten-by-the-nuclear-dragon/) where dr. Louis Slotin accidently slipped the screwdriver he used to separate two plutonium/uranium hemispheres:
"Immediately, all eight scientists in the room felt a wave of heat accompanied by a blue glow as the plutonium sphere vomited an invisible burst of gamma and neutron radiation into the room. As the lab's Geiger counter clicked hysterically, Louis used his bare hand to push the upper plutonium hemisphere off and onto the floor, which terminated the supercritical reaction moments after it began."
Big oopsie.
However gruesome the goal of these bombs, the rate of advancement in such a short timespan is nothing short of amazing. From the very first successful test (Trinity) to bombing Hiroshima: just 21 days. They were great days for science, but a shame to mankind that it had to come this far.
Hence, I imagine that many servicemen and women didn't see themselves as having a long life span. Maybe not consciously, but certainly subconsciously.
I have had a lot of oh shit moments in my days, but none gets close to dropping the plutonium onto the uranium and nearly detonating a nuclear payload.
Not possible for a plutonium device, and this is why the implosion method was so technically challenging. The plutonium must be transitioned from subcritical to supercritical very, very fast to achieve any significant nuclear energy release. In the final design, shaped plastic explosives, chosen for their very high velocities, were used to compress the plutonium from all directions simultaneously, very fast. Then, after the compression phase is complete, a carefully timed burst of neutrons triggers the nuclear fission event.
Very well written and interesting book.

And if cold-war nuclear lore is your thing, check out the photo gallery at http://atomic-annhilation.blogspot.com
A very well-researched book that challenges, adequately in my opinion, some of the fundamental assumptions about nuclear weapons. First and foremost, that "the atomic bombs ended the war with Japan".
And unlike a conventional weapon, it's pretty hard for a nuke of this design to accidentally explode.
The plutonium bomb was an implosion bomb, and had to be set off with the simultaneous (< 1us difference) firing of all the explosive lenses to get a symmetrical compression. This was done by charging up a big capacitor bank and discharging it through a krytron switch (like a thyatron or SCR; there's a turn-on gate, but no turn-off) into resistance wires used as detonators. There were no intermediate explosive detonators; they weren't consistent enough on timing. Any inconsistency on timing would cause the explosion to blow out on one side rather than achieving full compression. That still might produce a "fizzle yield", tons rather than kilotons of TNT.
"Single point detonation safe" bombs came years later.
Also note that the design tested at Trinity was not the design used on Hiroshima. The Little Boy design used on Hiroshima was a gun-type design that was so obvious it would work that it wasn't felt that any testing was required. The Fat Man design used on Nagasaki was vastly more complex (but much more efficient and scalable) that it was felt best to validate it before using it in war.
I occasionally wonder about the atomic bombings and the timing of everything. If the project had been delayed by a year or so, the war would have ended without them. But the development would continue, and the Cold War would no doubt kick off something like it did in reality. But without two examples of the horrors of nuclear war, would the superpowers have been as restrained as they were in reality? Rather than the first (and so far, only) use of nuclear weapons in war being two primitive bombs, it could have been hundreds or thousands, in a war run by people thinking that they were just doing a scaled up version of the city bombing of WWII. It seems like the timing ended up being extremely lucky.
Imagine the alternate version of something like the Korean War in a world where WWII ended without the use of nuclear weapons. Are the Americans going to refrain from using nuclear weapons on their enemies when the going gets tough in that scenario? My money is on "no", and I'd also wager that the nuclear bombing campaign would last a lot longer, since it would be initiated against countries with a much greater capacity to fight. For example, Mao really didn't seem to care about the potential devastation of nuclear war: "Let us imagine how many people would die if war breaks out. There are 2.7 billion people in the world, and a third could be lost. If it is a little higher it could be half ... I say that if the worst came to the worst and one-half dies, there will still be one-half left, but imperialism would be razed to the ground and the whole world would become socialist. After a few years there would be 2.7 billion people again."
How do we really know this? The Japanese were ready for a long drawn out decades conflict. The US forces were war-weary and war was draining the economy. This could have gone on with quite some time, or ended in a frozen conflict that would reignite periodically. Who knows, but a quick non-nuclear win was certainly not in the cards.
>would the superpowers have been as restrained as they were in reality?
Arguably, if the US used nukes on Chinese soldiers during the Korean conflict, as some generals advised, there would be no North Korea. We'd have a cowed China and built a single free and democratic Korea, essentially one large South Korea. Instead we have one of the worst regimes the world has ever seen as a client state of China, who uses China's political influence and muscle to threaten the West with nuclear war every day. So, progress?
Conflicts need to happen. The more we put them off or try to find conditional surrenders or half-assed peace, the more we're asking for more trouble down the line.
imho, the cold war thinkers had no love for humanity and weren't influenced by the bombings in Japan. From a game theory perspective they had no incentive to fight a full scale war because it would annihilate both sides quickly. Its a losing outcome for all. Instead, it led to dozens of brutal proxy conflicts in non-nuclear states paid for by the lives of young men of those states. How many died because of the advance of Communism in Asia? How many states failed because of it? How many did Stalin send to their deaths?
These are not trivial numbers. You still had conflict by the USSR's expansionist agenda, and a serious amount of it, just with conventional arms while nuclear arms largely protected the West from a Soviet surprise nuke attack. Countries without nukes were gristle for the Soviet oppression machine.
Your counterfactual about North Korea seems rather weak. You seem to assume that we'd drop The Bomb and then the war would be won and we'd all go home. But it probably wouldn't have won the war. The Chinese would have been happy to keep on fighting even with nuclear bombardment. All it would have done would be to greatly widen the scope of the war and turn a small proxy war into a general WWIII.
As for the rest, those brutal proxy conflicts were still way better than direct conflicts between great powers, especially a potential large-scale nuclear conflict.

In an article that finally appeared August 19, 1945, on the front pages of the Chicago Tribune and the Washington Times-Herald, Trohan revealed that on January 20, 1945, two days prior to his departure for the Yalta meeting with Stalin and Churchill, President Roosevelt received a 40-page memorandum from General Douglas MacArthur outlining five separate surrender overtures from high-level Japanese officials. (The complete text of Trohan's article is in the Winter 1985-86 Journal, pp. 508-512.)
This memo showed that the Japanese were offering surrender terms virtually identical to the ones ultimately accepted by the Americans at the formal surrender ceremony on September 2 -- that is, complete surrender of everything but the person of the Emperor. Specifically, the terms of these peace overtures included:
- Complete surrender of all Japanese forces and arms, at home, on island possessions, and in occupied countries.
- Occupation of Japan and its possessions by Allied troops under American direction.
- Japanese relinquishment of all territory seized during the war, as well as Manchuria, Korea and Taiwan.
- Regulation of Japanese industry to halt production of any weapons and other tools of war.
- Release of all prisoners of war and internees.
- Surrender of designated war criminals.
Is this memorandum authentic? It was supposedly leaked to Trohan by Admiral William D. Leahy, presidential Chief of Staff. (See: M. Rothbard in A. Goddard, ed., Harry Elmer Barnes: Learned Crusader [1968], pp. 327f.) Historian Harry Elmer Barnes has related (in "Hiroshima: Assault on a Beaten Foe," National Review, May 10, 1958):
The authenticity of the Trohan article was never challenged by the White House or the State Department, and for very good reason. After General MacArthur returned from Korea in 1951, his neighbor in the Waldorf Towers, former President Herbert Hoover, took the Trohan article to General MacArthur and the latter confirmed its accuracy in every detail and without qualification.
And as we can all agree, the emperor played at least as central a role to the Japanese leadership's legitimacy as the Fuhrer did to his.
What the atomic bombs did was made the emperor himself call on his people to surrender. This removed the ability for more hawkish parts of the Japanese leadership to continue a resistance effort, which some surely would have pursued.
Given the sprawling nature of Japanese positions, its deep cultural divides even between army/navy, its hard to know exactly who could authorize a peace treaty and if all other factions would listen to him.
They were no threat to anyone at that time.
And if we look at it from the japanese perspective: They never intended to invade the US. Their goal was to end the US blockade of Japan.
Not every single war has to end with an all out invasion.
There was probably no way to beat them without getting a lot of people killed. Leaving them alone was probably not a good option either.
I also feel a need to point out that Japan did invade the US in the Aleutians campaign, albeit a fairly insignificant and deeply out-of-the-way portion of the US. The Philippines could also be considered part of the US at the time the Japanese conquered it, although pretty loosely.
Yeah, one large, irradiated South Korea, ruled by a pathetic murderous dictator who would have friends in Washington D.C. instead of Moscow, and who would have killed people throughout the peninsula for being Communists[1], instead of being against Communists.
Yay for progress?
Fuck freedom and democracy. All those talk of freedom didn't do shit when Rhee murdered Koreans, when Park murdered Koreans, and when Chun murdered Koreans.
I know I can't really expect American soldiers to wage wars and get killed just to support the freedom of some third-world country they've never heard of, instead of ensuring the continuing political dominion of the US in a large portion of the world, but people could at least be honest about it.
How many died because the US fought the advance of Communism in Asia?
And why do you believe that it is even your damn business to interfere in countries that are thousands of miles away from the US?
By the way, the General that was responsible for the bombing Japan with nuclear weapons, Curtis LeMay (you can see his signature on one of the photos) was in favor of a nuclear war with the Soviet Union, and proposed dropping more than 140 nuclear bombs on Russia.
And yes, he was willing to lose US cities due to counter strikes. All that mattered to him was that the US had an advantage at the time, and could win a war.
He also insisted on invading Cuba during the Missile Crisis and almost convinced Kennedy. We are lucky that he failed, because there were already nuclear weapons on Cuba at that time (which he didn't know) and an invasion would have triggered an all out war.
Nowhere near as many that were systematically slaughtered by their own gov't.
A quick non-nuclear win was very much on the cards. The soviet union had just entered the war. The navy knew that it couldn't protect the homeland and didn't have any planes. There was, at the very least, a substantial faction in the cabinet that wanted to surrender, and had the support of the emperor in this. Can we be sure the war would have ended quickly? No. Can we be sure that the human cost would have been less than the ~200,000 civilian deaths caused by the bombs? Definitely not - conventional firebombing could have inflicted those kind of casualties if the war had continued for as little as another week or two. But a decade-long conflict or frozen ceasefire is really implausible; the balance of conventional forces was really overwhelming at that point.
> Arguably, if the US used nukes on Chinese soldiers during the Korean conflict, as some generals advised, there would be no North Korea.

You could equally argue that if the US had given up and pulled out of Korea entirely, instead of North and South Korea we'd have a country like Vietnam, which is doing pretty well. Or that if the Soviet Union had used nukes to conquer the world we'd have peace everywhere. Everyone thinks they're the "good guy"; any moral principle that would allow the US to use nukes would seem to allow other countries to do so too.
Its pretty amazing that the test procedure for determining the critical mass was essentially "stack these blocks of plutonium/uranium (by hand) until the neutron detector starts going off, and then take one away"
IIRC, that incident happened with the same sphere of plutonium, causing it to be called the "Demon Core".
It probably would have been more efficient to dilute the U-235 into reactor grade and use it to manufacture weapons grade Plutonium. However at the time the U.S. only had two bombs (the ones dropped on Hiroshima and Nagasaki) and it was probably judged politically expedient to drop two instead of one.
All of these processes were brand new at the time and mostly untested. Plutonium enrichment at the Hanford site used a reactor design that was validated well into the construction of the site. The Manhattan project already had a lot of risks, and they weren't going to attempt chaining projects for something unproven. Real experiments came after the war.
J. Robert Oppenheimer and Leslie Groves were a fascinating team, Oppenheimer being a physicist and Groves an Army general.
A must for anyone in technical management.

Nit pick: What you have described is the incorrect version in the movie "Fat Man and Little Boy". It was a knee-jerk reaction that stopped the supercritical reaction, and it was the beryllium outer sphere which was dropped, not the plutonium core.
Slotin was holding the top half of the beryllium sphere with his thumb which he immediately lifted up due to the intense heat.
Had he not made this instinctive move, everyone present would have perished and the area would have remained deadly until some other poor soul came upon the tragedy to stop the reaction.
The first-hand accounts of those present are in the thorough official report, which just happens to be collected in John Coster-Mullen's Atom Bombs book.
Eisenhower said "it wasn't necessary to hit them with that awful thing."
At the time Truman said Japan had been "repaid many fold" for Pearl Harbor. In these new images there is a bit of graffiti on the bomb allegedly written by a Rear Admiral: "a second kiss for Hirohito". It seems to me like the mood in the US camp was "let's hit them hard, teach them a lesson." rather than a more considered or balanced calculation.
Edit: in the documentary "The Fog of War" on McNamara, there is discussion of Curtis LeMay's decision to firebomb Tokyo. In that case there was apparently a degree of cool-headed calculation. http://www.errolmorris.com/film/fow_transcript.html
Some discussion of the nuclear bomb decision here: http://www.washingtonexaminer.com/it-wasnt-necessary-to-hit-... (I have no idea what the politics of that paper are, caveat lector)
"Stimson left the meeting thinking Truman completely understood the matter, and the final target order — with Hiroshima, Kokura, Niigata, and Nagasaki (the latter added only then) — was sent out.
But what did Truman take away from this meeting? We can look at Truman’s own diary entry from July 25th:
" This weapon is to be used against Japan between now and August 10th. I have told the Sec. of War, Mr. Stimson, to use it so that military objectives and soldiers and sailors are the target and not women and children. Even if the Japs are savages, ruthless, merciless and fanatic, we as the leader of the world for the common welfare cannot drop that terrible bomb on the old capital or the new.
He and I are in accord. The target will be a purely military one and we will issue a warning statement asking the Japs to surrender and save lives. I’m sure they will not do that, but we will have given them the chance. It is certainly a good thing for the world that Hitler’s crowd or Stalin’s did not discover this atomic bomb. It seems to be the most terrible thing ever discovered, but it can be made the most useful. "
This passage reflects an incredible misconception. Truman appears, here, to believe that Hiroshima was 'a purely military' target, and that 'soldiers and sailors' would be killed, 'not women and children.' But of course every city on that list was inhabited primarily by civilians. And by the calculus of war being waged, every city on that list had a military connection — they produced weapons for the military."

Japan was beaten. They had already offered a complete surrender, conditional only on keeping the emperor, which was rejected by the U.S. Their utter defeat and the hopeless state of their armed forces was well-known by the allies, since their communication encryption had been cracked months earlier.
The real issue was likely that the Soviet Union, positioned to become a formidable power in the post-war theater, had promised to enter the war against Japan on August 6. The Americans needed to make sure that Japan had been defeated by that point and that the U.S. would occupy Japan, not Soviet Russia. Hence the rush to drop the bombs before that.
Also, there was no uncertainty about the lack of military significance of Hiroshima and Nagasaki, the contemporary reports state this clearly, they even warn about the presence of American POWs in the area (which was ignored and they were incinerated along with the hundreds of thousands of Japanese civilians).
Hiroshima was the city that supported the Kure Naval Base and associated anchorage. Nagasaki was a major port that was an adjunct of the Sasebo Naval Base. Those were two of the IJN's four main bases. The impotence of the IJn at this point notwithstanding, I think it is unreasonable to claim they had little military significance.
Whether or not that justified levelling them in what you can argue were just live-fire nuclear tests is a different question.
This is inaccurate. Much fewer than 200,000 people were killed immediately (totaled across both bombings), including both incinerated and not, civilian and not.
http://en.wikipedia.org/wiki/Atomic_bombings_of_Hiroshima_an...
Casualties and losses: 20 U.S., Dutch, British prisoners of war killed 90,000–166,000 killed in Hiroshima 39,000–80,000 killed in Nagasaki Total: 129,000–246,000+ killed
It doesn't say if these are all immediate casualties (does it even matter), but it does mention estimates for Nagasaki immediate casualties is between 22,000-75,000.
Wikipedia gives an immediate death toll of 70,000–80,000 people, of whom 20,000 were soldiers for Hiroshima and 22,000-75,000 people for Nagasaki. This is far from hundreds of thousands of incinerated civilians.
I don't think 120,000 lives qualifies as splitting hairs. I thought I was delivering good news, but judging by my karma, it has not been well received.
Are you saying the Japanese offered to surrender, with the only condition being maintaining the emperor, prior to the bombing of Hiroshima? My understanding is that was the terms accepted after the atomic bombings and the declaration of war by the USSR.
They already knew that they could take Japan, it would be nasty, but they could do it. So from that point of view, the bomb was unnecessary. But from a post-war perspective, the West was facing the prospect of a strong aggressive Soviet front. The A-bomb put an instant chill on all post-war aggression and helped encourage the worlds armies to stand down just a little bit.
I think in hindsight it's also worth pointing out that people in general are pretty terrible at judging the consequences of things of that scale. ie. You can describe just how big an explosion a nuclear bomb is going to make, but until one is actually dropped and the casualties start coming in, you don't really comprehend it fully. If those bombs hadn't been dropped, the aversion to destruction might not have been fully ingrained in the minds of every commander and it could well have meant that the Cold War would have turned "Hot".
Pretty scary stuff considering that the main brunt was born by civilians.... oO;
The ultimate aim of an attack on a town area is to break the
morale of the population which occupies it. To ensure this,
we must achieve two things: first, we must make the town
physically uninhabitable and, secondly, we must make the people
conscious of constant personal danger. The immediate aim, is
therefore, twofold, namely, to produce (i) destruction and
(ii) fear of death.
Whilst that strategy may have worked in Japan with the atomic bombs it was hardly successful in Europe. And surely the impact was on the high command and political leadership rather than normal people.[1] http://en.wikipedia.org/wiki/Strategic_bombing_during_World_...
There is a 1950s fictional film by Akira Kurosawa called "I Live in Fear" which tells the story of a man driven mad by fear of radiation from a nuclear war. For better or worse it is easy to forget now what a catastrophic thing the introduction of the bomb was for everyone.
What if 4 or 5 years after the war it turns out that the president had a wonder weapon that could have ended the war in a week and saved 1/2 a million GI's - it would have been the end for the democratic party when that came out.
The notion that the alternative to the bombings was an invasion is an utterly pernicious falsehood. It is a matter of record that Japan had offered to surrender prior to the bombings, conditional only upon retaining the emperor. Those terms were subsequently accepted, after the bombings. The "peace" faction's strategy was to accept the surrender before conducting the bombings.
US POWs ended up picking up the tab for My Lai.
(But keep in mind, Judaism, Hinduism, Islam, Buddhism and others all regulate revenge instead. Revenge is certainly justified under those moral systems, and the revenge is usually bigger than the event that "justified" the revenge. Judaism, but especially Islam is especially famous for having revenge punishments so extreme (I should say so extremely stupid) that they have triggered civil wars on occasion (of course these come from the Roman Empire's late-empire laws, which had a justice system that can reasonably be called "based on terror"). Which moral system is right ?)
The moral issue here is the duty to stop or at least contain moral wrongs in progress, e.g. this Unit 731, the Soviet Union, ... The key difference being that revenge is after the fact and is unnecessary. The key thing about revenge is that it makes society worse off in the short term, both the person taking revenge and the person being punished (e.g. kids destroying a toy rather than giving it back).
To fight moral wrongs in progress the moral position is that it is justified to use any amount of force, but comparable force should be tried first. Collateral damage should be avoided, but if you can't stop a criminal without causing collateral damage, then it is acceptable to, for example, destroy property (if the police destroys your front door chasing a robber, you will not receive compensation, nor if they burn down your house, though insurance usually covers this). If someone fights, beat him a bit and lock him up. If someone has a knife or a gun and is (trying to) kill people, shoot him. If a country is raping and killing half a continent, ...
This differentiation can be found in the bible, and in any sane moral text. Hell, it can be found in the UNCHR (united nations convention on human rights).
Consider this: even if that "youngster" wasn't filtered out from his contemporaries due to his skills or character, he still came from a generation that was engaged in a war that had taken the lives of friends, family and neighbors. It was also probably also obvious by then that you don't mess around with bombs, regardless of how they worked.
I'd wager that the average "youngster" during WW2 was a great deal more responsible than their modern-day counterparts of similar age.
This sort of appeal to superficial appearances generally doesn't hunt on HackerNews.
Whee, wartime is fun!
EDIT:
Even more amazing when you consider that they weighed about 10k pounds.
(La Wik says the US Air Force is currently paying $27,000 per tail kit.)
I also haven't gotten into the business and logistics costs of pulling this off, but consider the fact that there is not even a RFP for such a device in existence.
Imagine today you have that device in your table. Ok. What is your next step. Just show up at the Pentagon with it in your bag?
A lot of that costs money (unfairly probably) and that is one of the reasons soldiers sometimes end with crappy hardware that costs some astronomical amounts.
Reliability is obviously a concern, but the procurement process should force contractors to open their designs to qualified competitors after a certain period of monopoly profits to recoup their research expenses, sort of like the same way that brand name drugs are eventually forced to compete with generics. Just because these designs are generally national security secrets doesn't mean that the original developer should own the equivalent of an infinite patent on the technology.
No, where you're really going to get burned in dev is hooking the bomb up to the aircraft's targeting system. That's a world of pain right there. The best solution might probably involve making a Bluetooth widget that hooks up to the aircraft and then talks to the bomb via radio. They could be pre-paired in the factory. Not ideal though. You're also going to need to spend a ridiculous sum of money on sales, just to get your foot in the door.
A 500-pound dumb bomb consists of about 250 pounds of steel and 250 pounds of high explosive. Plus a fuze.
When manufactured in large quantities, $3000 in 2014 dollars seems like a reasonable cost.
(Most of the ones in the US Air Force's inventory were manufactured decades ago.)

Simultaneously, 42,000–150,000 local civilians were killed or committed suicide, a significant proportion of the local population.
Human affairs are sometimes terrible, but they often take the least terrible path out of all terrible paths. This is evidenced by the fact that the cuban missile crisis didn't result in an all-out nuclear war, and also that these bombs were dropped on Hiroshima and Nagasaki rather than Americans invading Japan, which would have been far more devastating.
http://en.wikipedia.org/wiki/Operation_Downfall
Casualty predictions varied widely but were extremely high. Depending on the degree to which Japanese civilians resisted the invasion, estimates ran into the millions for Allied casualties.
I upvoted you because I agree that everyone should be terrified at the prospect of war, because war only happens when people aren't terrified of it.
The allies had complete air and naval superiority and Russia had joined the the Japanese war theatre.
If you have read the ethics of atomic bombings in any detail you are already aware of the details, so I would refrain from linking to wikipedia. To push your POV that the bombing was entirely necessary and entirely morally right is immoral.
[Edit]
As requested below: here are the detail about the military unneccesity of the atomic bombings. http://en.wikipedia.org/wiki/Debate_over_the_atomic_bombings...
There are other debates around this, but this discusses only if Japan would have speedily surrendered without the Atomic bombing.
It's fine to say that Japan would have surrendered without invasion, but such a strong assertion needs to be backed by equally strong evidence.
EDIT: An excerpt from your link:
This conclusion assumed conventional fire bombing would have continued, with ever-increasing numbers of B-29s, and a greater level of destruction to Japan's cities and population.
It seems hard to argue that literally firebombing an entire civilization into stoneage living conditions was more ethical than forcing a quick political decision to surrender and stop the madness. Can you imagine trying to live without basic necessities? Even if nobody was dropping bombs on you directly, you, your family, and everyone around you would be the definition of misery for the duration of the firebombing. The firebombing didn't simply destroy military targets. It also decimated infrastructure that we take for granted, such as the ability to deliver drinkable water, or to seek medical treatment at hospitals. How many were to die a miserable death due to the firebombing before Hiroshima and Nagasaki could objectively be called the more ethical decision?
Also, the above analysis assumes both sides had perfect information. But information during wartime is asymmetric. It's entirely possible that America had no knowledge of the Japanese political framework at the time the decision to drop the bombs was made. If the Japanese were broadcasting their intention to surrender before the bombs were dropped, that would be different, but it doesn't seem like that was the case.
Would you mind helping me understand why firebombing was more ethical than the destruction of Hiroshima and Nagasaki?
This was shown by post-war inquiries. Japan had already offered a complete surrender, contingent only on preserving the emperor. They had been trying to surrender since April, according to documents leaked by the president's Chief of Staff, on roughly the same terms that the Americans ultimately accepted.
The rush to drop the bombs was that the Soviet Union had promised to join the war against Japan on August 10, giving the Western allies only a few days to make sure that they would be the ones occupying Japan, not the Soviets.
A cynic might also suspect a bit of enthusiasm among U.S. military to field test the power of their new weapon.
Note that even with the bombing and the Soviet intervention, there was a military coup aimed at preventing the surrender that very nearly succeeded. The contingent of the Japanese government that felt it was better to be obliterated than to surrender was large and powerful.
One could certainly argue that they would be overcome as the realities of the situation set in, but one could also argue that they wouldn't.
It is, as you say, debatable. Which makes it odd that you just dismiss the other side so readily.
They may well be right, but American Military officers making decisions couldn't possibly know any of that. All they can know is what the Japanese government has said and done, and anything that their intelligence sources can pick up, which may or may not be believable. Everything they would have seen up to that point says that Japan is ruthless and determined to not surrender, and they can only be convinced otherwise if it's clear that they face total destruction otherwise. I can't see how any information available to them points to any other conclusion than that the bomb should be dropped as soon as it's ready to bring an end to the war as quickly as possible.
How about using those bombs on or over invading fleets of Japanese - if Japan ever actually planned to invade the US?
Things I've read indicate that there was an actual lack of trusted comms between the Imperial staff and the U.S. I believe things were going through the Soviets. Some credit that with leaving enough gap to make any offer of surrender much slower and harder to verify. And there was allegedly a power struggle within the Imperial chain of command.
You might have visions of the U.S. systematically destroying any Japanese war power that ventured out for conquest while leaving the home islands untouched, but that kind of shepherding requires a degree of total military superiority we did not posses at the time.
Of course it can be said that the purpose of the use of any weapon is to win and thereby end the was sooner, hence saving lives in the long run. In that case the purpose of any bomb, tank, landmine or gun is to save lives.
Surely the force of nuclear weapons could have been demonstrated without actually dropping it on a concentration of living, healthy people.
Atomic weapons are a natural evolutionary step up from conventional explosives, which are a natural evolutionary step up from clubs and rocks. All this talk about atomic weapons being qualitatively different (as opposed to quantitatively different) is mostly hyperbole, with one exception -- only wealthy industrial powers can create them ... so far.
> Surely the force of nuclear weapons could have been demonstrated without actually dropping it on a concentration of living, healthy people.
The people in charge decided that a demonstration wouldn't stop the war or the need to use the new weapons, and later events proved them right. Contrary to what many Americans believe, the Japanese didn't surrender because of the atomic bombings, but because Russia invaded Manchuria, a development the Japanese saw as much more dangerous than atomic bombs.
If that is the case, then that proves they were dead wrong about their justification for the necessity of dropping those bombs in the first place. Why tell everyone "we need to bomb" in order for Japan to surrender when you knew it wouldn't stop the war?
For various political reasons (I'm not justifying this, only explaining it). The Manhattan Project began in response to the perceived threat that Germany might create an atomic weapon. In 1945, with Germany out of the picture, and with no alternative, people began to talk about using it against Japan. It was realized that, if we didn't force Japan to surrender to us, they would surrender to the Russians, with unimaginable postwar consequences.
Again, I'm only explaining the thinking of the time, not justifying it.
After the war, it was discovered that Germany was nowhere near creating an atomic bomb, but it came out that Japan was actively pursuing this class of weapon and was technically farther ahead, lacking only the raw materials. In the closing days of the war, a German submarine was intercepted trying to deliver uranium to Japan for use in a nuclear weapon they planned to build and use against the U.S. :
When the US entered the war, one of their first moves was unrestricted submarine warfare, meaning any Japanese ship is sunk on sight, regardless of who or what is onboard or where it is heading. It continued with sinking many naval fleets, re-invading many islands, generally resulting in the death of basically everyone in the Japanese garrison, as it was part of their code to kill themselves or carry out suicide attacks rather than surrender.
Continuing on, we have the unrestricted aerial bombing of basically every city in Japan. The only reason Hiroshima and Nagasaki were relatively untouched so late in the war was that they were exempted from conventional bombing for the purpose of evaluating the effectiveness of the atomic bombs when they were ready. Many of the conventional bombing raids caused greater death and destruction than the atomic bombings.
In light of all of this, suggesting a demonstration of the bomb seems kinda pointless. The Imperial Japanese administration would probably interpret such an act as saying that America didn't have the courage to carry out major attacks, thus encouraging them to hold out longer and requiring more destruction in the end to force a surrender. The bombings were terrible, but the real suffering was the war itself, and the only way to stop it was to force the surrender of Imperial Japan as quickly as possible. Against such an enemy, the best way to end the war with as much of Japanese society as possible still intact was to demonstrate total ruthlessness in doing anything in our power to destroy Japanese infrastructure and kill Japanese citizens as quickly as possible.
1. The "Little Boy" device, cylindrical in shape, was a U-235 gun-type device that was so simple in its design that it was dropped -- on Hiroshima on August 6, 1945 -- without having been tested first. The U-235 was extraordinarily expensive to produce, taking up a large percentage of the Manhattan Project budget and several years. Two independent programs using different methods were designed to produce sufficient U-235, which needs to be separated from the much more abundant and non-fissioning U-238 isotope. The expense of extracting U-235 is the reason that only one such bomb was used, and only a few were ever built.
2. The "Fat Man" bomb design used an isotope of plutonium (Pu-239) that was bred in fission reactors in Hanford, WA and Oak Ridge, TN over a relatively short time and at much lower cost. This bomb was tested at the Trinity site on July 16, 1945, in advance of its use on Nagasaki (August 9, 1945) because its implosion design was much more complex than the uranium bomb.
3. All modern fission weapons, and the trigger devices in fusion weapons, are design descendants of the Pu-239 "Fat Man" device that was dropped on nagasaki.
What they were ignorant of, I'm pretty sure, was the actual magnitude of the destruction caused by the devices. My father was about 10 yrs old at the time, he was deeply effected by news reels at the time. The tragedy was horrific.
" ... But if you graph the number of people killed in all 68 cities bombed in the summer of 1945, you find that Hiroshima was second in terms of civilian deaths. If you chart the number of square miles destroyed, you find that Hiroshima was fourth. If you chart the percentage of the city destroyed, Hiroshima was 17th. Hiroshima was clearly within the parameters of the conventional attacks carried out that summer. ..."
Contrary to your statement that the attack was considered unremarkable, reports of the attack were initially disbelieved by the Japanese government because they knew of nothing that had occurred that could have caused such damage: "It was generally felt at Headquarters that nothing serious had taken place, that it was all a terrible rumor starting from a few sparks of truth."
From http://www.abomb1.org/hiroshim/hiro_med.html#SUMMARY
The ultimate effect of the atomic bombings on the surrender compared to the Soviet intervention is highly debatable, of course, but it wasn't irrelevant just because it wasn't the most devastating attack of the war.
That's like saying we'd treat a shooting incident where 500 people died the same as 500 individual murders.
I agree with that idea. Apart from the fact that they were single-plane attacks, there was little that set the Hiroshima and Nagasaki bombings apart from what happened to almost every city in Japan. Yes, radiation sickness is awful, but so are napalm burns on half your skin.
One thing that I wonder about whenever this subject comes up is whether it would have been cheaper to deploy use conventional bombs against those targets. It would have been fairly easy to send a thousand bombers with conventional payloads (or just 200 that made 5 sorties each)
We can point to things people said and did in the past and make informed judgements about the plausibility of various reasons they had for doing what they did, but again: anyone who asserts bluntly and with confidence that "Japan would have surrendered if..." or "Japan did surrender because..." isn't helping.
Japan surrendered after Nagasaki was bombed. Some people think this shows that Hiroshima alone was not enough to convince the Japanese government that the new weapon would turn the tide of war against them.
Russia declared war on Japan after Hiroshima was bombed. Some people think this was important to Japan's surrender, but would it have happened without the bomb?
Japan had a history of fighting for every inch of territory. Some people think a conventional invasion would have resulted in a rapid conquest.
Area bombing in Europe had a relatively small effect on the Axis war effort, and an awareness of this was growing within the Allied command. Within military circles there tends to be a feeling that if something isn't working the best thing is to do more of it. The bomb was more of it. Thus, the ineffectiveness of area bombing in Europe may have contributed to the decision to use the bomb in Japan.
And so on...
It is worth noting that war itself is almost always strongly motivated by counter-factuals. "If we just bomb the enemy they will surrender" (they don't: they become more dogged in defense until they demonstrably face total destruction). "If we engage in horrific acts of terrorism the enemy will run in fear!" (they don't: terrorist organizations that employ violence against civilians have a zero--yes, zero--rate of effectiveness in achieving their goals: http://belfercenter.ksg.harvard.edu/publication/792/why_terr...)
All we can say with anything remotely resembling certainty was that the bombs did drop and the war did end. We can make some informed guesses about why both sides decided the way they did. We can say virtually nothing with any certainty at all about what would have happened if any major decision had been different... except maybe one.
What if Japan had never attacked Pearl Harbor? This is a counter-factual that people who are wont to make blunt, confident predictions about "what would have happened" had the Allies never destroyed Hiroshima or Nagasaki are generally surprisingly silent about, yet it is one of the few things that would plausibly (not certainly) have avoided the subsequent destruction of those cities.
Arguably, Japan's attack on Pearl Harbor was the best move they could have made, considering their position. They did succeed in limiting US naval power in the Pacific for the 6 months that Yamamoto estimated.

Sure, if it hadn't worked, they may have tried again, and the next attempt may have led to all these things, but fact is, it DID work, and everyone in these photos contributed to it (knowingly or unknowingly).

Edit: He's also the guy who deduced the most probable internal configuration of Little Boy, and built an inert 1:1 scale model which was presented to and signed by the living members of the 509th Bomb Wing.
It is a bit unfortunate that many of the captions and the sequence of photos are inaccurate. There are many misses regarding which bomb was which and on which plane it was loaded and on which city it was felled.
So, look at the pictures and ignore the captions and then read up on Wikipedia to understand the bigger picture.

"Its casing". Why do people have such a problem with it's and its?
...inside Fat Man's casing...
I assume you knew that though and were just being an ass.
If you remember (and care) that its and it's are two separate words, then you should be able think your way through it. It's could legitimately be possessive or a contraction, but its can only be the possessive.
Anyway, I agree with you that it's tricky enough that we shouldn't be assholes about it.
* ...about to be placed in Fat Man's casing.
* ...about to be placed in the bomb's casing
* ... about to be placed in its casing.
One of those is not like the others.
My, His, Hers, Ours, Yours, Theirs, Its.
Not Me's, He's, She's, Us's, Your's, Their's, It's.
English is an easy language. Most languages use a lot more words than all that to convey all that. English speakers don't have to deal with the singular second person, with a separate objective noun for you/he/she, with neutrals (heck, barely at all with the feminine), and so on.
So make an effort. Get its right :)
What is relevant is that there are two forms: it's and its. Its easy to mix them by non-natives like myself.
No-one ever writes She's or Us's, but "It's" is valid as is its. It's easy to deduce that one should not write us's but it's not that easy with it. :)
To summarize, comparison to other personal pronouns is irrelevant since "it" has a special combination of rules.
I think you're having a hard time because you're overcomplicating the matter. "its" is the possessive of "it". "it's" is a contraction of "it is". Possessives adjectives: My, Your, His, Her, Their, Its. Possessive pronouns: Mine, Yours, His, Her, Theirs, Its. You have four less to remember than with most languages :)
You said it yourself: you're not sure how "it" is special. I'm sorry, I cannot help you any further. Maybe others in this thread can.
Bob's going to Bob's house.
(Bob is going to the house Bob owns).
Look, a bear! It's going to its cave.
(Look a bear. It is going to the cave it owns)
"its" is a weird special case.
You're being far too generous to us natives by implying that this is only a problem for non-natives.
Doesn't check out, sorry.
The regular form of possessive is 's. That is, when it's right to add an s to a noun indicate possession we add an apostrophe. This is more regular than a lot of english rules. So now there are pronouns. They are a bit weird, carrying some strange stuff from germanic languages about changing the word based on the case (sometimes). For the most part, it's pretty straightforward still.
Now we get to the word its. Yeah, it's a pronoun, but it follows the possessive pattern of adding an s. So 'it' follows the pronoun pattern of changing the word, but it also phonetically follows the regular noun pattern of adding an s.
In this one special case, there are two patterns being followed at the same time. Except not really, because unlike all the other cases where the s is appended for possession, we don't mark it different.
This is of course because there is a form of the phonetic 'its', which is spelled "it's" . This word is very similar to its, but it really is a contraction (a special word that actually means two words, but we're lazy and drop some of letters from the second word) in this case, "it's" is ("it's"'s :) ) short for it is. That phrase of course is not about possession, but it does describe a quality possessed by the thing referred to by "it".
Of course on top of all this, we have yet another use in english for the 's construct. It is related to the "it's", because it not only denotes possession, but also denotes a contraction with is, or with has (which itself is a completely different rant - have and is are arbitrarily used in all sorts of languages) like described above for it's , but more generally.
That means the the sentence:
Bob's going to Bob's house.
Is a correct way of using the 's in two different meanings...
Bob is going to the house Bob owns.
Yet, if was talking about a robot...
Robot is going home. Its house has its charger and it's going to plug in.
So yeah, English is super duper easy! I mean, how hard is it for our pattern matching machines to not realize that contracting with is means 's, that possession which is phonetically an s sound is spelled 's, and pronouns use different words for different cases, these are all pretty regular occurrances, EXCEPT when talking about spelling the pronoun its, which despite its appearance and phonetics of being a pronoun that follows noun rules, is actually a separate word arbitrarily. I mean, who would ever get confused by the 's pattern not applying in this one case? It's a special case of a special case and should be extremely obvious.
Amiright?
He. She. It. That's all you have to deal with. You have to know whether the subject is male, female, or indeterminate in some way. There's maybe a couple of exception (like boats being refered to as She and such) but other than that, you literally go by genitalia.
In most other languages you have to take into account whether the subject is male or female and whether the subject should be referred to as plural as a form of politeness; if their sex is unknown or indeterminate you have to know whether the word itself is masculine or feminine (or neutral!). Shall I go on?
Oh and that's not even mentioning languages with different grammar rules for the various different kind of persons. You have singular and plural. That's it. Some languages have singular, plural-few, plural-many, some, none, all, and they all have their different grammatical rules.
Boo-hoo, you gotta remember whether to put an s or not. Some languages have to remember dozens of different suffixes to put at the end of the word depending on the forementioned rules and a bunch more, including how the word itself is written.
Come on.
Given the vast amount of energy wasted on memorizing spelling quirks, compared with nearly all other languages, it's not surprising that many people, including you, frequently make other mistakes in their written English. When a language consists more of exceptions than rules one can't be too harsh on people for wrongly applying a rule.
To use the programming language you used elsewhere: English is PHP... it's easy to use as badly as everybody else uses it.
"placed in its casing" vs. "placed in ours casing"
I prefer to see English like I see Python. Younger, easier, more flexible and more self-aware than the languages it draws its roots from, and fun enough that it has a lot of influence on every other language.
English is more like Ruby than anything else.
