I didn’t watch the whole thing but his dismissal of uranium 233 as “hard” to turn into a bomb is flat out wrong. It has many of the properties of plutonium 239 and would be perfectly fine for an implosion fusion/fission device. You just need to chemically reprocess the fuel from a reactor to get it, just like they did with plutonium. The first Soviet fusion bomb was uranium 233 instead of plutonium for christ sakes. https://en.m.wikipedia.org/wiki/Uranium-233
