“I know this: They have 10,000, roughly, kilograms of fissionable material. That’s broken up into roughly 460 kilograms of 60% enriched uranium, another 1,000 kilograms of 20% enriched uranium …They manufacture their own centrifuges to enrich this material. So, there’s almost no stopping them. They have an endless supply of it. The 60% materials, Sean, can be brought to 90%, that’s weapons-grade, in roughly one week, maybe 10 days at the outside. The 20% can be brought to weapons grade inside of three to four weeks.”
