Cmv:nuclear weapons are the only thing keeping the world from going to complete hell:
With how close the world has come to annihilating itself because of leaders who've been a bit trigger happy (Cuban Missile Crisis) I truly believe nukes are pretty much the only reason the world isn't in major conflict right now.

The Cold War for example. If the US and the Soviets didn't have their nuclear arsenal, what reason would Stalin, Khrushchev, etc have for NOT invading the rest of Europe? They could've easily done so and not much the US could've done to stop them. 

Our greatest and most terrifying weapons are pretty much our salvation and force us to cooperate even if we don't like each other.
