Does the world NEED to balance out nuclear power? No, the world in itself shouldn't have nuclear war missles to begin with. Even so the U.S. does have such power and we need to think about this.
The U.S. isn't on the verge of destroying any mass of people. Nor will it anytime in the near future. The U.S. has it's downfalls but it is not so savage as to actually use this against anyone injustly. We're one of the more rational nations. But, to play the devil's advocate; the extremist point of view:
Mr. Paranoid: But..But.. the U.S is gonna take hold all the power.. and and..my little third world country can't take on ANY nation, let alone one with nuclear power.. No.. the existance of these bombs are parallel to Hitler's inspiration for the Holocaust..the U.S. will have absolute power.. over time.. the U.S. will kill us all.. ahhh! :::cowars in homemade bomb shelter:::
Nope. Not gonna happen. Like I said before, I don't like the idea of these heinous death traps existing but, because one person plays with fire, should the next? In my opinion, no.
