I'm teaching an applied ethics course this summer, and I'm thinking of covering war and terrorism again, which I haven't done a full-blown unit on in a few years, at least not with any focus on Iraq. I've got a great book that has excellent philosophical treatments of pacifism, just war theory, torture, individual rights and national security, the war vs. law enforcement models of fighting terrorism, and other general discussions of current issues on the subject. I've also got a book that I'm thinking of using that makes a case for fitting the justification for the 2003 Iraq invasion into just war thought, and even though it's not a heavily philosophical treatment it should be easy for me to provide that side of things.
What I don't have is a high-quality critique of the Iraq invasion in terms of just war theory. Does anyone know of such a thing? I would ideally prefer a low-priced book (especially something less than $20), but if I have to settle for an article or two then that would be better than nothing. There's probably much more critiquing the invasion than supporting it, simply because academics tend to fall that way in their political alignment, but I don't know much about published works, since most of my reading on the subject has been online. Any suggestions?
