Just because some people did some nasty shit doesn't mean they're gonna do it again. In WW2, there wasn't a side in the war that didn't commit war crimes. Including the majestic and heroic United States. The world has 'advanced', however. Russia isn't 'hardcore', it's just Russia. The shit you're talking about was the Soviet Union, which was a scary dictatorship masked under communism. It was Stalinism, which isn't different from Fascism or whatever Hitler had in mind. Also, invading the States would be retarded. At least 10% of the population are citizens equipped with personal defense weapons. Nuclear weapons would be bad for the economy and would create a second Great Depression. If history has taught us anything, it's that the people will probably rise up against the military, rebellion and such. Nuclear weapons are also pretty much banned, if you fuck up, the UN is gonna rape your ass. You gotta look at the big picture. lol
