On 9-11, we discovered that we cannot escape from the world. To me personally, this was a life-changing experience, and I realized, as did all Americans, in a way that is impossible to describe, that we were not protected by the two oceans. It was necessary to eliminate threats before they showed up on our doorstep. I agree that we should not be getting caught up in far away wars. But I believe Iraq was central to our war on terrorism.
