This just goes to show that you haven't got a clue, you lousy little rat. Except for your negativity and racism and all. Ever heard of mutual destruction? Wasn't that the reason why the Cold War never turned hot?
Well there are two examples,
1. WW1 remember how it turned out? It was well planned nobody would want to attack anybody since it would just make a huge catastrophic war, instead a bloody slaughterhouse.
2. Cold war as you mentioned, so both possibilities are most likely to happen.
