the reason warbots bother me is that people (including the decision makers) haven't seemed to figure out what exactly they're trying to accomplish when they go to war. What is the U.S.'s goal in Iraq? With no clearly defined goal, how do we know when the war is over? P.S. I know the economic reason for the iraq war (http://www.time.com/time/magazine/article/0,9171,998512,00.html http://www.time.com/time/magazine/article/0,9171,998512,00.h...) but that doesn't explain why we're still there.
