Okay, let's follow this thought. The US, and the whole western world, rely on advanced weapons that blitz attacking forces, literally try to attack weapons only to the point that some weapons try to spare the operators of said weapons, and certainly try to avoid hitting innocent bystanders, but have trouble sustaining an attack. The idea is essentially to discourage attack by destroying anything that moves in the opening phases of a war, if possible in the first 10 minutes.
BUT it has massive advantages: it doesn't kill many people, it does minimum damage, even to military hardware. Even their high prices are a security measure: they require a massive diversified economy behind them to produce these weapons (so even if the US gave Iran engineering specs for nukes, Iran can't build those weapons, and can't build the infrastructure required to build them either. The same goes for most weapons. Iran and Russia have no use for Western weapons, despite what they themselves think)
The "dream" Western weapon is a "space laser", when Khamenei comes out of his hole and has a meeting with his commander ordering deaths in Syria ... that before he even finishes the sentence, a hole develops in his face. We can't do this (yet?), but that's the dream. One death, thousands to millions of people saved, and yes, billions of dollars saved too.
What western weapons want to avoid at all costs is what's happening in Ukraine and Russia: society vs society, economy vs economy, war of exhaustion, what's also happening in Israel-Iran. Decades-long sustained economy-destroying wars. Redirecting entire countries' output towards military for prolonged periods of time. Economic output. Cultural output. Even the output of women's wombs.
The alternative is what communists (and "ex-"communist states that inherited such weapons) do (Soviets, North Korea, ...). Mass, sustained wars of exhaustion. Dedicating all of a country's entire resource base to war, for decades. Economy. Culture. Everything. Including babies, including population, including you and me if they can. Their weapons are very different: their weapons are cheap, easily concealed, worthless, and follow the philosophy of "kill, kill, kill". Weapon can't reach target? It still blows up. You are cheap and can't get component X? Just stick a wooden block into it. Weapon still fires, still kills, probably not the enemy, but it still kills. Artillery out of shells? The human meat wave running towards the enemy STILL leaves. For some reason the aim is off to the point you have no hope of hitting the target? Still fire, still kill, just not the enemy. Weapon gets intercepted? It tries to do maximum damage, even to their own forces. The point is sustained killing in a war of exhaustion, maximum misery, maximum damage. This demoralizes the enemy. It also demoralizes their own troops, but that's why you have barrier troops, security services and torture. That's why hamas and Iran keep getting caught torturing their own people, occasionally even their own soldiers.
And, of course, they consider enemy civilians a weapon. That's why Putin gives interviews in the west, friendly, laughing, pointing out all the problems in Western societies while being extremely understanding of the concerns and worries of the person in front of him. That's why Nasrallah was a "friendly grandpa". He is nothing of the sort, obviously, a ruthless killer and rapist. That's why Sinwar is "a family man", a "hero that fought to the end" (he hid in a pre-prepared cellar safely away from his forces, then got found and killed outside of the combat zone, literally accidentally when trying to rob Palestinians for food after running out, after sending out his lieutenants to try to do it for him). That's why Putin even finances Greek extreme-right political parties, and Iran uses Qatar to finance social science departments in the US. Believe it or not but in reality neither the Iranian nor the Qatarese governments see the use of studying psychological effects of gender-switching and LGBTQ preferences of pre-adolescents. They are paying for weapons, to be used against western societies, nothing else.
Communist doctrine consider even womens' wombs advanced cannons: they produce and launch weapons at the enemy. Russia has not changed doctrine. Same with hamas and Iran.
Socialist's reaction to any setback is the same: throw more people at the conflict to die faster, at an ever increasing rate. That's what Putin is doing now in Ukraine. People think last months' increase in deaths/day (over 1500 Russian victims per day, sustained for >40 days now, up from ~100 per day at the start of the war) is Putin's reaction to Trump's election. It's not. It's Putin's reaction to the war stalling, according to communist doctrine. More death, faster. If the Russian army stalls again, and it will, Russia will throw more bodies at Ukraine. Until India put a stop to it they even kidnapped Indians and put them to the frontline. If Hezbollah fails to achieve anything against Israel, and it will, Iran's leaders will respond by killing more Iranians, killing more Syrians faster, killing more Lebanese faster. Or they will try to.
And, as people are reporting, you should not make the mistake of thinking this is stupid: it's working. It's at least a partial success in Ukraine. Well, it is if you consider territorial and possible future financial and geopolitical gain at the cost of hundreds of thousands dead a success. And you can be pretty sure Putin doesn't just consider the resources and territory gained in Ukraine a success, but that he considers the deaths a success too (less effort for the Russian state towards these minorities, more war, "less trouble people" as he put it in one answer).
A nice illustration of this difference is US vs Russian nukes. The US published their plans. If a US nuke were to get intercepted, it blows up in a mode to AVOID a nuclear cascade, it blows up chemically to "salt" the fissile material. It self-destructs, not just to avoid a nuclear explosion, but to make all components of the bomb, including the fissile material, utterly unusable for weapons. They even keep the casing intact in hopes of avoiding even radiation poisoning if someone were to collect the warhead and put it under their pillow. Russian nukes that get intercepted blow up. The Kremlin has confirmed that if a Russian Nuke is intercepted, even if it's still over Russian soil ... it initiates nuclear detonation. Famously, if the Kremlin is destroyed, Russia threatens it will automatically launch Nukes ... including at Russian cities. Not just Russian cities, Brussels and Washington too but including Russian cities. And of course, he considers it the job of Western armies, not his, to protect Russian cities against this. You can be sure that the IRGC has orders to start massacring Iranian cities' population if the central government were to fail, and that hamas will massacre Gazans and WB Palestinians when they feel really their hold over them slipping.
Do you really want the US and/or Europe to switch to this way of fighting? I don't. You don't either.
