i've touched on this topic before, and it is one with extremely wide margins of error on account of broad variability in theory and a pretty abject lack of precise situational data
but we're waging the most pointless war in history (a title with no shortage of candidates), all for the specter of a thousand pounds of enriched uranium in iran
the us consumes 100 million pounds of enriched uranium per year to fuel its 90 or so reactors, which is about half of global consumption at 200 million pounds. the nuclear industry often quotes a figure measured in billions of years for reactor fuel supply, but this is based on the capability of breeder reactors, of which there are exactly zero operating power plants at present
the us arsenal of about 5000 bombs is estimated to contain about 1 million pounds of enriched uranium, or about 200lbs per bomb, although again this varies greatly per each due to intended design yield and age (this is divided into about 1500 warheads awaiting dismantlement, 1700 deployed and 2000 in reserve)
the global supply of uranium ore -- were we capable of mining and enriching every last speck of it, which we are not, and if none of it goes to remanufacturing warheads, which some will -- would last about 90 years at present rates of consumption. due to the fact that the vast majority of uranium ore is and will remain unextracted, a supply shock is forecasted in about a decade
the manhattan project required about 20 million pounds of congolese uranium ore, which was exceptionally enriched in its natural state at about 20%. this manufactured two 150lb warheads to be detonated over japan (as well as prior and subsequent tests). the manhattan project would not have been possible without uranium from congo. when einstein and szilard starting writing letters to advocate for development of the bomb, they wrote to a belgian cabinet minister first (due to its colonial control over the congo until 1960) before they contacted roosevelt. the vast majority of naturally occurring uranium is less than 1% pure, and only possible to enrich with a robust and preexisting industry to process it
iran has never manufactured and was never going to manufacture warheads, even aside from the bombs we've been dropping on their enrichment facilities for decades and aside from israel's campaign to assassinate nuclear scientists. i am contradicting iaea analysis for the un, because it is plainly obvious to me it was politically motivated and not grounded in trivial if obscure scientific fact
i've touched on this topic before as well, but the un was convened in direct response to the advent of the bomb, and the five permanent members of the un security council are the same five countries with the largest nuclear arsenals
the only reason russia and subsequently china were able to develop nuclear weapons was because the rosenbergs leaked the design of the bomb from the manhattan project to the ussr, having correctly surmised that a unipolar nuclear armed body geopolitic would swiftly become unlivable. they were executed without trial
this has been the entire, openly stated, purpose built design and intent of the un since day one. to ensure that only allies join the security council. if they could have prevented russia and china from joining this group, they would have. this is why iran has not been allowed to develop a nuclear energy program. because it is an adversarial state to the us
this delicate balance of power was established by what history considers the greatest minds and diplomats. i've criticized them individually as well, but the point i'd like to make today is that this balance was so delicate it took one fucking idiot (puppet, supported by a coterie of abysmal, greedy and power grubbing cronies, which is to say ordinary capitalists) to destabilize it
