I think the comment from the ITER communications chief that you can’t use fusion for proliferation is bunk though – it’s true for these small devices, but part of the planning for tokamak reactors is to generate tritium using a breeder blanket … last time I looked, tritium was a key component of all hydrogen bombs, and for D-T fusion to work as a practical energy source you need to generate unprecedented quantities of the stuff. Which would seem to make it easier to make fusion warheads. Just sayin’.
