icegreentea2··on U.S. to Withdraw 5k Troops from Germany, Pentagon Says
There are two broad reasons why the US has troops in Germany (and in Europe overall).

1. Because the Europeans wanted them there. NATO was a big security blanket, and certainly since the end of the cold war, up to say... 2014, America -wanted- a compliant Europe.

2. Because Europe is an amazing springboard into the middle east, and America just can't help but get itself involved in dropping bombs on the middle east.

1 ties into 2. A compliant Europe is less likely to raise objections to being used as a forward base for bombing Iraqis and Iranians. It's only in the last 10-15 years that the US realized that perhaps it was/had squandered it's lead to China, and dropped the ball (Europe at fault too) on properly containing (or addressing) Russia, and it would sure be nice if it could focus on the Pacific.

icegreentea2··on U.S. to Withdraw 5k Troops from Germany, Pentagon Says
The articles mention withdrawing a BCT (which is ~4000 people) form Germany.

The US currently has 2 BCTs "fully" in Germany. The 2nd Cav Regiment (a Stryker unit.. so infantry mounted on 8x8 APCs) and an Armoured BCT on 9 month rotation (so tanks and IFVs).

There have been a bunch of studies indicating that the rotational ABCT costs more than even a truly forward deployed ABCT. My bet is that it's the ABCT that is going to get withdrawn. It's both the flashier unit, and likely has the highest impact on freeing up money. This also lines up with the withdrawal timelines... since the unit is rotational, they just need to wait for the end of rotation, and just... not send another. Much less disruption.

While the timing was obviously conjunction with current events, this draw down was likely to happen at some point in this term, even in absence of Iran things. Trump literally tried to do this at the end of his last term.

icegreentea2··on How an oil refinery works
The total energy supply figure is a primary energy mix - for the fossil fuels it represents the thermal energy of the fuel. You can look at the final energy consumption section a bit lower to get a different picture taking into account conversion losses.

Some crude averages from https://www.eia.gov/energyexplained/oil-and-petroleum-produc...

~50% gasoline, ~25-30% diesel.

icegreentea2··on Ukraine's drone commander has Russian oil, troops and morale in his sights
Ukraine has concretely demonstrated their ability to perform deep missile/drone strikes (on the order of ~1500km) onto Russian strategic and economic assets.

Ukrainian drone capabilities in the near battlefield (up to ~20-30km deep) are also not contested. Russian milbloggers will openly talk about the difficulty of massing and movement in that area due to the saturation of drone coverage (and btw, this challenge is more or less symmetric).

So the article is not likely exaggerating any of their capabilities. However, it is exaggerating via omission.

In terms of deep strikes, the question is what the success rate of these missions are, what cadence can they sustain, what's the constellation of Russian lapses that have to line up for a successful strike, etc.

Another known area of weakness (that the Ukrianians are working hard on) is the middle range. How to strike quickly at targets of opportunity in the 50-500km range field. This was/is a capability that things like GMLRS and ATACMS provided, but I imagine the Ukraine is forced to ration those munitions carefully.

icegreentea2··on Ukraine's drone commander has Russian oil, troops and morale in his sights
Ukraine's "long range attack drones" are really just cost optimized cruise missiles. Long-range strike against strategic targets is something you can handle without man in loop control. For example, the original Tomahawks could do terrain radar matching (+inertial guidance) for navigation, and had a fully onboard camera based system for terminal guidance.

icegreentea2··on Where did my taxes go?
If you do tax revenue as % of GDP, you get the US falling at about 25%, with the OECD average sitting around 35%.
icegreentea2··on Hungary Is a Laboratory for Illiberal Nationalism. The Results Are In
I don't think the poster was saying that Orban wasn't bad, just that Cato saying something about it isn't particularly signifying.

Also... neoliberalism is basically what you think of when you think "right-wing billionaire word salad" from like 6 years ago. Neoliberalism is the the idea of elevating "the market" to the absolute primacy of... everything. Neoliberalism is coined relative to the traditional "liberalism", specifically the part of traditional liberalism that supported free trade and marketization.

The Cato Institute was literally founded by one of the Koch brothers, and has been staunchly neoliberal/libertarian. It stands in opposition to many of the policies of the current far-right/ex-right movement, because those policies call for a fusion of market and government that actually is fundamentally incompatible with neoliberalism. Furthermore, we should be aware that the populist surge that is at least partly powering this surge is itself a reaction to the conditions that neoliberalism (and institutional capture) has created.

icegreentea2··on US and Iran agree to provisional ceasefire
No one has agreed to the Iran's 10 point plan, and they're not going to get all of it.

The provisional ceasefire actually goes against the Iranian proposition. Point 2 explicitly is "permanent end to the war, not a ceasefire".

Iran backed down a bit here from their maximalist aims (which is what the 10 point is).

icegreentea2··on Lunar Flyby
SpaceX is an amazing success story, both as a commercial story, and as a story of government-industry cooperation. NASA should be proud and commended for fostering SpaceX.

The question is why does SpaceX stand alone? Why did ULA stagnate? Why can't NG make SRBs that don't have nozzles that fall off? Why can't Betchel build a launch tower on time? What is it about government contracts in these other areas that led to all of this under performance?

The US benefits by having SpaceX around. It would benefit even better by having many SpaceXs around.

Oh, and also I believe it's generally understood that NASA provided very little funding for New Glenn. They gave BO a lot of money for HLS, but that's relatively recent (2023). New Glenn has been in the works since 2013 and was mostly bankrolled by Bezos, with some USAF/DoD money kicked in.

icegreentea2··on Lunar Flyby
There's a lot of potential in the announced changes and what SLS/Artemis might be able to become. This shouldn't prevent us from being critical of what SLS/Artemis most definitely has been for the previous 10-15 years.

And don't be fooled about the SLS launch cadence. As recently as summer 2025, Artemis III was still a nominally a 2027 manned lunar landing (https://www.nasa.gov/blogs/missions/2025/08/18/nasa-begins-p...). It got moved to a 2028 manned lunar landing in early 2026, before being converted back to a 2027 manned test flight.

The plan for SLS also does nothing to make it more capable (though hopefully less expensive). The cancelled exploration upper stage is being replaced by Centaur V, which is a less powerful stage. Isaacman refuses (I think rightfully) to really pin down on if there a future for SLS past Artemis V. If Isaacman chooses to cancel SLS after Artemis V (which I think is a defensible course of action), then SLS would represent a ~17 year long program that cost at least 41 billion dollars that netted 5 mission launches.

And characterizing it as "moving the lunar space station down to the surface of the moon" is... kinda falling into the trap. Lunar Gateway was supposed to launch ~2028 (along with Artemis IV - from the era where Artemis III was the first lunar landing). Gateway was a gongshow, and was delayed, and now cancelled. And now the new plan says the habs (the part that people think as an actual base...) happens in Phase 3 starting in 2033. The sort term elements they are trying to reuse from gateway into near term (think ~4 years) base projects are very "ancillary".

It remains unclear if NASA will infact be able to up the launch cadence of SLS to meet the double 2028 launch requirement. While it was clear that Gateway made... very limited sense for great expense, and the new plan is certainly ambitious with what I think is a stronger value proposition, it's also basically exactly as pie in the sky as gateway back in 2019.

The fact that I am doubting NASA's ability to execute now, is the very cost of SLS (and friends).

icegreentea2··on Lunar Flyby
The absolute cost isn't the problem, it's the value that we're getting from it. SLS and Artemis are both incredibly expensive and ramshackle programs, and regardless of how bad the rest of the USG might be in terms of their cost, or value, if you are a true space fan and a true American space fan, you should want this little corner of humanity to hold itself to a higher standard.

Acceptance of over costing and under delivering is exactly why the US is stuck with SpaceX as its prime space launch provider. It's only through the miracle of the vanity of billionaires that there's even a realistic second choice (Blue Origin) that might develop.

It's also this type of attitude that let's us be in a situation where we honestly don't know how well the heat shield will work on reentry (SLS launches are so expensive, and so slow to build and prep to launch, that we cannot fit in a uncrewed mission between 1 and 2 to test or validate fixes or models).

If Artemis as a program succeeds, it will be despite the incredible graft, pork, and ass covering, not because of it. I want Artemis to succeed because the achievement will be beautiful and amazing, and I want everyone to be safe and sound. I want Artemis to fail, to force a reckoning. I still believe that America has great things to offer to the world, but it's not going to be able to do that by muddling it's way through and cobbling together random pork filled programs into a vaguely inspiring shape.

icegreentea2··on Iran Is Not Blocking the Strait of Hormuz. It's Running a Toll Booth
I don't think its meaningful to talk about commercial/diplomat as such clear categories at this level.

Bypassing dollar clearing is only really a commercial concern because it is a political/diplomatic concern.

Diplomacy is the act of non-violent interactions between countries. Commerce is (generally...) a non-violent form of interaction between countries. High level diplomatic actions enable commerce (of various forms and levels), while commerce creates incentives for diplomacy, and creates the strength for a party to perform diplomacy.

icegreentea2··on Iran Is Not Blocking the Strait of Hormuz. It's Running a Toll Booth
There's other news floating around from Citrini saying similar things - the actual substack post (behind a paywall https://www.citriniresearch.com/p/strait-of-hormuz-a-citrini...), and some news coverage - https://www.cnbc.com/2026/04/06/wall-street-firm-sends-analy...

Being able to put up toll booths on the Strait is another knife to the body of international law and the good old rules based order.

icegreentea2··on Is Germany's gold safe in New York ?
Western reflexes towards isolationism comes from two factors:

1. Long-term backlash against unchecked globalization. Every western country has to come to grips with the long-term impacts of the deindustrialization that globalization has enabled - this impacts their domestic societal stability, their long-term economic growth, and their ability to act internationally and independently.

2. One particular western leader (who happened to come to power, at least partly riding the wave of the backlash above) has accelerated this trend by taking the possibility of trans-Atlantic (+plus a few Pacific trends) tradebloc to form "globalization lite" as a middle ground solution (honestly, I have no idea how viable this would have actually been), and took it behind the shed and shot it, and then burned the corpse.

Globalization was bearable in part because America did infact run the game, and tended to run the game reasonably well. US aligned nations could all see China growing in strength, but they all figured that as long as they played their role and played nice, that when the time came, they could join the US in whatever new game it wanted to play, or join the US in helping push back. What they perhaps did not count on was just has careless America could be, or that America would want to stop playing with them at all.

Towards your point on confidence and trust. As others have pointed out, Trump has also violated trust in all sorts of ways. Trump delights in norm and trust breaking, as a form of dominance display - both as meat for the base, but also to satisfy his own impulses. But perhaps worse, I think a lot of people are now also calculating that Trump could easily misuse or violate trust without really knowing it. Iran should have clarified to everyone that the Trump administration is willing the act on deeply flawed (or perhaps absent) second order (or even move-countermove) planning.

icegreentea2··on Iran's IRGC Publishes Satellite Imagery of OpenAI's $30B Stargate Datacenter
The Iranian's regime's minimal goal is regime security. To that end, it aims to apply maximum pressure/cost on Israel/US, and hope that they will relent at some point. Iran has no other means to actually cause the Israel/US to stop (as in, it lacks the ability militarily deter or defeat).

Iran recognizes that it is not just the actual damage, but the credible threat of damage that incurs pressure/cost. For example, there are piles of ships holed up in the Gulf - Iran has the capability to strike at them, but they don't need to. Publicity is part of magnifying the threat.

Iran likely lacks the capability to actually assuredly destroy any single target of its choosing. Iran instead likely has the capability of destroying maybe 1-10% of targets that it actually chooses to engage. However, it can hold hundreds of targets at threat to try to ratchet up the pressure. In addition, by casting an ever wider net of claimed targets, when it does get around to attacking, it's more likely to be able to construct a narrative of "calling their shot".

icegreentea2··on With one million displaced, Lebanon turns to digital wallets for aid
Seems there are two parallel developments here:

a) Rise of alternate forms of organizing trust. People distrust government or other organizations, and turn to alternative forms of organization and trust.

b) Rise of digital wallet/transfer systems that are fundamentally about charging for throughput/withdrawals. The article mentions that banks are restricting withdraws - presumably because banks need deposits to stay liquid. Whish on the other hand doesn't care - it makes money as a % of each transaction.

icegreentea2··on Gold overtakes U.S. Treasuries as the largest foreign reserve asset
The events of the last year certainly have a role to play, but the overall effect is just the result of trendlines that have been in play for quite a while.

Here's a world gold council (i know...) review/survey of central banks gold holdings from mid 2025 (https://www.gold.org/goldhub/research/central-bank-gold-rese...). It notes that gold purchases (by mass) have been elevated going back to ~2023.

Gold prices have also been on an upward trajectory ever since 2023 (https://goldprice.org/gold-price-history.html)

Whatever is happening now is bigger than actions over the last year.

icegreentea2··on TSA lines are so out of control that travelers are hiring line-sitters
If you scroll down on the page, it'll show that the user fees only offset ~20% of the overall security expenses.

In addition, most fees (including most of the TSA fee) collected by the US Federal government isn't earmarked - it just goes into the general fund.

icegreentea2··on The 'paperwork flood': How I drowned a bureaucrat before dinner
As another post mentions, this definitely fits into the wider genre of morality/revenge/malicious compliance porn. Regardless of if this is real or fiction, AI generated or not, it's still porn.

Porn isn't bad, but thinking that porn adequately reflects reality, or that behavior within porn is blanket appropriate for real life is.. not good.

icegreentea2··on Olympic Committee bars transgender athletes from women’s events
It feels one sided because the author is an outsider - as the author readily admits - "It has been brought to my attention, however, that my blasé attitude toward sports makes me an outlier".

Turning to some actual numbers - this 2024 survey tells us that only ~15% of respondents said that their children participate in club sports or independent training (note that the categories are not exclusive). The same survey also says that ~10% of respondants think that their child can compete in professional sports, or be a national level team member. Finally, a similar 10% say that the "only the best players should receive time in games" is a fair policy at your child's age and level.

https://www.aspeninstitute.org/wp-content/uploads/2025/06/Na...

I think the point of the article is to maybe highlight how large the gulf might be between an typical outsider (and looking at the numbers above... and reminding ourselves that only ~50% of American youth are involved in organized sports at all), someone who is somewhat "in the game", and those who are really playing it (that 10% from above).

icegreentea2··on Asbestos, talc, and The Lancet's 1977 publication
The argument is that the opportunity cost outweighs the marginal gains.

The original argument (it's linked is that):

* The major manufacturers are already restricting asbestos

* That asbestos contamination is detrimental to cosmetic quality, and therefore manufacturers have a self-interested motivation to meet their claimed safety specifications

* In any case, the most likely sources of contamination are those which were not yet determined to be cancer causing

* Oh, and we should regulate medicinal talc first before cosmetics

icegreentea2··on Missile defense is NP-complete
There are multiple tiers of missile (and ballistic missile defense).

Especially with ballistic missiles, the longer the range, the faster the inbound warhead will be in the terminal phase (roughly). So longer range ~= faster meaning more difficult to intercept.

"Iron Dome" is the name generally used to describe Israel's lowest tier set of defenses. Very roughly Iron Dome is designed to defend against stuff that you could plausibly fire from the back of a truck, and have a max range of around ~50km.

Very roughly, these were intended to take on something like GMLRS (realistically, massed volleys of unguided rockets) - these are rockets that one or two people could conceivably manhandle, and are traveling in the neighborhood of Mach 2-3. One of the key innovations of Iron Dome is its ability to quickly ascertain and design on which rockets were unlikely to strike valuable areas, and only engage the actually threatening ones.

The next tier up is David's Sling, and then Israel's wider set of high performance anti-ballistic missile systems. Returning the the range <-> speed thing, we'd need something like a medium range ballistic missile to get from Iran to Israel. For something like the Shahab-3, that's like ~Mach 7 during re-entry.

If we step up to IRBMs (so something that China might use to strike at Guam), we're probably talking like Mach 10.

icegreentea2··on Missile defense is NP-complete
Air defenses do not need to be 100% effective to be... effective.

Russia cannot keep Ukraine from targeting their oil infrastructure, yet here Russia is, still fighting on. Ukraine cannot prevent Russia from targeting their energy infrastructure or apartment buildings, yet here they are, still fighting on.

If we're talking about strategic/civil air defense, then you must figure out what's tolerable to your population (and how to increase and maintain that tolerance), and then figure out all the means to reduce the incoming attacks to below that tolerance. That must include the full spectrum of offensive, counter offensive, defensive, and informational options.

icegreentea2··on “Collaboration” is bullshit
It's a provocative title, but I think this section better captures his scope of argument - "Collaboration-as-ideology has made ownership and responsibility feel antisocial, which is a hell of a thing, given that ownership is the only mechanism that gets anything across the finish line.", as well as "But there’s a huge difference between communication and collaboration as infrastructure to support individual, high-agency ownership, and communication and collaboration as the primary activity of an organisation".

I think the author has identified that most organizations both fail at effective collaboration, and also use collaboration to paper over their failures.

I think the author maybe over-corrects by leaning on the idea that "only small teams actually get stuff done", and honestly I don't think anyone should be using SLA Marshall/Men Against Fire as an analogy for like... office work (if nothing else, even if you take his words at face value, then the percentage of US infantry who fired their rifles went up from 15-25% in WW2 to ~50% in Korea due to training improvements), but I can get behind the idea that a lot of organizations are setup to diffuse responsibility.

I also do think it's interesting to think about building the Pyramids. For the vast majority of people involved... I don't think modern audiences would call their work relationship or style "collaborative". Usually we use "collaborative" in opposition (at different times) to "working alone", "working with strict boundaries", and "being highly directed in what to do". Being on a work gang, or even being a team foreman is very much "no working alone", but those were also likely highly directed jobs (you must bring this specific stone to this specific location by this time) with strict boundaries.

icegreentea2··on Centuries of selective breeding turned wild cabbage into different vegetables
Because I love cabbage... the blog post shows "Gai lan" as an Asian example. There are so much more!

You are probably aware of napa cabbage, but there's also Taiwan Cabbage (goes by other names of course...) https://www.westcoastseeds.com/products/taiwan-cabbage

It looks a lot like a flatter "green/european" cabbage. It's leaves and stems are finer and softer than a European cabbage, while still being pretty crunchy (as opposed to napa). Compared to European cabbage, you could actually just stir fry these.

Gai lan is just one variety of "Chinese broccoli" - there are multiple varieties with different stem thicknesses, and "branching ratios". This will let you pick to suit your preferred level of crunch and leaf area to coat with sauce =)

And finally, all of the bok choys are also part of this family.
