I think by 2050 practically every nation will have acquired the technical capabilities to produce a nuclear weapon. If countries like north-korea and Iran can develop the technological know how, other countries should be able to do that too. It is more a political question than a technological one. Do we uphold the non-prolifiration treaty or will it be ignored in the new world?

Exactly, the Ethiopian Empire has a Minor Arsenal of Nuclear Weapons (About 150), and they recently became industrialised before Ww3, all nations do have the ability to make nukes, the question is have they already made them?
