Kremlin says US has rejected its proposal that Russia take Iranian uranium stocks

Untill a dirty bomb goes off and the analysis indicates the material came from Iran, and public response gets split between blaming Iran and blaming Russia. The fuckery Russia can get up to with deniable uranium stock is no bueno.

Ya the simplest way to do it is inspect Russian ships before they enter the Persian gulf to make sure they’re empty, then inspect them again when they leave to get a detailed measurement of how much Iranian uranium they have on them. It’s my understanding that we know almost exactly how much enriched uranium Iran has, so it’s just a matter of keeping track of how much is taken out

International oversight in russia now? They aren't a reliable partner to deal with. 

expired. atomic bombs need upkeep and a tiny variation in mass can change the expected critical mass results. although uranium-235 and plutonium are "relatively" stable, they will decay enough over the decades to cause issues. the hydrogen bombs are a whole lot worse, because they include the pesky atomic bombs and tridium, which has the half-life of only 12 years. now, can these be kept up to date? of course. do i believe that the USSR was doing that while spending all the money on chernobyl? no. do i believe that 90s russia was doing that while being ripped apart by oligarch enriching themselves? no. do i believe that 21st century russia was doing that with putin in charge? no. why? because nobody ACTUALLY knows anything about russia's nuclear capacities. when they allowed foreign investigators to check on them, they only saw "things that they say are nuclear bombs." we see what state the russian army was in. it was believed to be the second most powerful army in the world. they are now in year four of a war with ukraine. putin likes to act tough, but he isn't spending money on things like upkeep when he can send it to his private bank account, and, in reality, there is little difference between a real nuclear bomb and a fake one if everyone believes they are real. only the most dementia ridden psychopath would actually use them, and say what you will about putin, but he isn't that crazy.

Degradation of fissile material tends to involve the fissile material undergoing toxic slow fission. The process will slowly turn each kilogram of uranium into other, far less fissile elements, most with increasing toxicity. After a certain point, the warhead won't detonate when triggered due to insufficient critical mass. Wait too long, the warhead will simply become too radioactive to fix, and risks exploding all on its own from meltdown (really only applicable to specific warheads as they degrade). In real life, the process typically involves manually disassembling the nuclear material and either storing it with other nuclear waste or recycling / re-refining. Long before any of the above dangers occur.

They need to be maintained. They're very expensive to maintain.  And we're talking about a country whose army has been documented riding donkeys as they invade their next door neighbor Even if they've been maintained comparable to the rest of Russia's military hardware, that would still indicate a lot of duds And in all likelihood, investment went into things more immediately useful once the war started. Meaning nuke maintenance may actually lag behind that already low standard

Logic has no place in politics. Most people are too stupid to read past a headline, and politicians (and journalists) know this. So the story would be spun that trump gave Russia nukes, and some dumber people would eat it up. So you're right, it doesn't make sense that people are too stupid to comprehend that...however it's still a useful political point nonetheless.

I'd bet everything I have that this admin is embezzling billions.
