People always go back in time and try to explain uranium enrichment to Hitler. Why not make it easy for him guys: just create heavy water or a ***graphite moderated reactor using natural uranium, then extract ***Plutonium 239 from the spent fuel like India did. There are two such experiments under the Third Reich, the first of which failed due to *boron contamination of the *graphite moderator, so it's probably a soft spot for der Fr. Soothingly explain to him that ***synthetic graphite makes it easier to separate out the ***boron vs ***natural graphite. That's how we made Fat Man. It's also why ***Israel is so ANNOYED by other Middle Eastern nations having any nuclear power plants, Hey would it kill you to at least pretend to listen?
