9/11, no. They were going to attack Iraq anyway. Afghanistan, partially. 9/11 made Afghanistan possible but we still shouldntve gone in.
I have to add here that it is generally not the conscious motive of a warmonger/neocon to go to war simply for profit. They genuinely believe that war, pre-emptive or otherwise, is a good solution to problems (real or imagined). The problem is when that particular worldview is formed by working in the defense industry, both public and private, that does thrive on war.
