Point well taken, and thank you for clearing things up a bit.
At the same time, isn’t most of the “science” involved already done in Iran and from now it’s a matter of spinning a lot of centrifuges to purify the high-yield stuff?
Does it really take 10 years of spinning centrifuges to get the amount needed?
And if so, how did we do all the centrifuge spinning on relatively short order in 1943,44,45?
It’s not about how much material you have, it’s about how you detonate it. Serious yield (thermonuclear, megaton bombs) is achieved through “blow back”, you use the initial blast to get an even more critical mass on the second stage. And that, it turns out, is really hard to do.
