Bush just happened to have the extreme misfortune of being an American president during time of war.
Every sitting president during times of war have been hugely unpopular, especially with the way it is now days with segments of our own (liberal) population actually hoping that we lose the war and our families and country are destroyed.
That being said, my favorite Bush euphemism is the word "strategery" which he spoke of while discussing strategies for the war in Afghanistan.
