The fact that our largest presence in the world is our massive military is going to dictate how we engage with the world.

If you polled the military in Afghanistan as to how many think we should be there or not, the numbers would probably be similar to what the U.S. population believes. That's not because they're watching the news. But, hey, they are out there risking their lives. No one likes to be criticized and it really sucks to be criticized when you're risking your life.

I have a deep-seated skepticism about the morality of violence. Violence is almost always morally corrosive.

The simple and terrifying reality, forbidden from discussion in America, was that despite spending $600 billion a year on the military, despite having the best fighting force the world had ever known, they were getting their asses kicked by illiterate peasants who made bombs out of manure and wood.

We also need to look at precedent before making these decisions. Instead of listening to Muammar Qaddafi's rhetoric, we should look at how he's behaved. The fact is he's been making concessions recently. He gave up his nuclear weapons. He allowed hundreds of Americans to evacuate Tripoli. Did he crack down on his people who revolted? Yes, but that's not so unusual. For me, it's always a failure of diplomacy. Our willingness to immediately turn to a military solution is disturbing.

During the invasion of Iraq in 2003, the military conducted only a handful of drone missions.

If the thumbnail version of the Iraq war was that Bush lied about WMD, the thumbnail version of Obama's war in Afghanistan is that the generals pushed him into a war he didn't want to fight.
