Failure of Warplans
In a recent press meeting President Bush said something that is so insightful that it should be an admission against all and every war:
"Listen, every war plan looks good on paper until you meet the enemy, not just the war plan we executed in Iraq, but the war plans that we have been executed throughout the history of warfare."
So i would say we look at the history of warfare and say warfare in itself is a failure. Let there be peace then.
