maybe. i only hope for world peace though.

i think america, after the soviets successfully tested the atomic bomb (thanks to melita norwood), intentionally and gave nukes to various countries in secret (japan, china, israel, india, etc.) and also those countries might have uranium buried under them, and those countries have a big enough nuclear sector / intellectual community to research the bomb. anyhow, soviets did the same (north korea) and those countries at least have nuclear powerplants and missiles with a decent range, enough industrial strength to militarize all those things and make nuclear warheads rather quickly if they're not struck first in a nuclear war.

imaging after the war where your normal script kiddies can get uranium somewhere in a no man's land and use far more advanced tech (3d printing, much better missile guidence that might come straight outta their mobile phones or smartwatches) to have a little fun. they can threaten entire cities with those things. this is not like anything before where you can just take the damage and expect majority of the people to grow tired of war. there'd always be extra-jumpy sociopaths willing to nuke others, but in that world they play a much bigger role. (unless we colonize a couple of other planets and can survive on them without help from earth.)
