Glenn Greenwald nails it:
How long are we going to continue to do this? We invade and occupy a country, and then label as "insurgents" or even "terrorists" the people in that country who fight against our invasion and occupation. With the most circular logic imaginable, we then insist that we must remain in order to defeat the "insurgents" and "terrorists" -- largely composed of people whose only cause for fighting is our presence in their country. All the while, we clearly exacerbate the very problem we are allegedly attempting to address -- Terrorism -- by predictably and inevitably increasing anti-American anger and hatred through our occupation, which, no matter the strategy, inevitably entails our killing innocent civilians.
