I guess I see a serious moral difference between a side that drops leaflets warning civilians of incoming attacks and encouraging them to move/leave, so that military targets and weapons caches can be destroyed with a minimum of civilian casualties, and a side that straps bombs to 15 year olds and sends them into a Sbarro's to blow up 40 people who are trying to enjoy lunch.
Perhaps you don't see any difference, and that's your prerogative, but that kind of thinking ("we're no better because we do rotten stuff too") is exactly what is going to lead to the downfall of Western civilization. What scares me even more is that a lot of people think we deserve it. What scares me even more than THAT is that the people who think we deserve it are almost without exception educated an enlightened liberal thinkers who cherish the progress made in the name of liberty - desegregation, women's sufferage, the gradual triumphs of the gay rights movement, etc. These things would fly right out the window across the globe in the absence of countries like the U.K. and U.S.
