One can say that nuclear weapons have been the biggest peacemaker known to man. It's hard to imagine another World War since the advent of such weapons. Furthermore, the nuclear weapons today wield a power that cannot even be compared to the ones that were dropped on Nagasaki and Hiroshima. I don't think any superpower today wants another global war knowing that it would spell total annihilation for all those involved.

We also shouldn't discount that the world today has so much more globalization. Just about every country has become interdependent on each other.
