Certainly some valid reasons here, or at least reasonable points that can be addressed even if the conclusion is wrong. Also some reasons that are, of course, mutually exclusive, but you never implied that a single person would hold all these views at once. Some are vacuous ("War is terrorism?"), and a few are just plain dumb ("War encourages fascism?" like in WWII?)

I would recommend as an exercise for the student going over the list again, and seeing how many of these consequences result from America hiding under the bed and allowing murderous tyrants to take over large portions of the planet, something that, unfortunately, only wars can sometimes prevent.

BTW, it's kind of beside the point to keep playing the "Iraq had nothing to do with 9-11" card. Most of the same people complaining about possible war with Iraq were just as firmly against using any military action against Al Quaeda and the Taliban in Afghanistan, and for most of the same reasons you listed.
