The major countries are way too good at war these days to have a serious fight... we'll all be killed.

The lethality of their power is greater than ever. Their capacity to impose control over the politically awakened masses of the world is at a historical low. In earlier times it was easier to control a million people - literally - it was easier to control a million people than, physically, to kill a million people. Today it is infinitely easier to kill a million people than to control a million people. It is easier to kill than to control, and of course that bears directly on the use of force, particularly by societies that are culturally alien, over other societies. -Zbigniew Brzezinski, 2008
