France is working with partners on a plan over how to respond should the United States act on its threat to take over Greenland, Foreign Affairs Minister Jean-Noel Barrot said on Wednesday.

      You could centrifuge enough Uranium to get mostly U235 in a gun-type design (the Hiroshima bomb) and use that to trigger a larger fusion bomb.

        It may be possible but as far as I know the US built nuclear power plants to create plutonium with which they built the fusion bumbs.

        500 or so warheads would be needed for credible deterrance. Are centrifuges really enough? There is also not much uranium left unless we want to return to Mali who won’t just sell us theirs as long as we oppose Russia.

              290 is plenty enough to reduce the USA population centers to rubbles I’d think. They may be developing interceptors against ICBMs, but multiple countries, France included, are also developing things like hypersonic glide delivery vehicles that are even harder to intercept, so I don’t think it changes the equation much.

          Yes, the Nagasaki implosion design used Plutonium instead, which requires a reactor.

          Uranium exists all over the world. Saying there isn’t much left and that Mali is some magical last place where it exists is…not correct.

          PS: Mali is mostly gold (e.g. Mansa Musa), it is Niger that seems to be a large Uranium producer.

            Germany was in Mali to help France secure their Uranium supply. There are other sources, but to which does the EU without France have access?

            Thanks for the map.
