If World War III starts, I feel that when history looks back our time period; we will be seen as the aggressors and the catalyst for the war. There was a legitimate reason to invade Afghanistan. I could even possibly concede for argument sake that we had barely enough reason to justify an Iraqi invasion. But a preemptive strike on Iran, and North Korea(who seems to be cooperating) would be disastrous. Even intervention in the Russia/Georgia conflict would be disastrous. It is time for America to stop policing the world. We need to settle our business in the middle east, and then leave as quickly as possibly. We need to fortify our borders from outside attack, and then begin to fix America's internal problems.
