Are you going to be realistic in the terms of actual nukes in a country, say Russia? I think 20,000 odd nukes in a game engine such as HOI just wouldnt work out. Are you going to like put 200 nukes for Russia, 300 for USA, 100 for China etc etc. And if a country starts a nuclear program, will there be punishments for it? Like the US right now is raising a fit for a supposive North Korean Nuke program...
