Bismarck
The Iron Chancellor
Speaking of ICBMs I think it's unrealistic for the Manhattan Project to be able for ALL civs to build nukes. Soviets only managed to explode an a-bomb b/c they infiltrated the MP.
Are you sure? I don't think there's any concrete evidence one way or the other.
Iraq doesn't have nukes yet (we hope). Other nuclear nations include France, Britain, China, and Israel. South Africa, Brazil, the Ukraine, Kazakhstan and others used to be in the nuclear club, but they gave up their weapons.
I don't think it's TOO unrealistic that Manhattan Project gave nukes to all civs -- after all, in the Civ II world, only the top 7 (at most) civilizations are playing. Any of the top 7 nations today could easily get their hands on nukes, if they don't have them already.
