Or, given the seeming inevitability of war, should we take seriously the possibility that there are good and bad reasons to go to war?

Should there be absolute limits on certain actions, or might any action be justified under extreme emergencies of war? Has the "war on terror" raised unique challenges to our understanding of ethics in war?
