Hey Guys,
I'm not sure if a thread like this has been done but I'm going to post it anyway.
How long could the discovery of using Nuclear Fission (and Fusion) as a Weapon of Mass Destruction be put of for? The use of Nuclear Fission can still be used as a source of energy, and there can still be radiation used in small amounts as a form of poison, but not a large scale weapon.
How could this happen? And how would this affect the world? What would both the short and long term affects be?
