As the wealthiest country with all the blessings that we have, do we have an obligation to help the outside world? I think we do, as we have an obligation to help everyone within our own borders. The problem is that this automatically gets translated into: "What's the point of having a huge military if we can't bomb people?" That's the problem that I have. Our foreign policy is essentially our defense policy.

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.

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

And there's this talk that we're asking soldiers to make the greatest sacrifice, but the reality is that civilians bear the burden of war more than the combatants. You're much more likely to get accidentally blown up or killed by a death squad than you are to die in a firefight.

General McChrystal wanted to be on the cover of Rolling Stone.

I did an embed in Afghanistan on the Pakistan border in 2008. One of the things you realize when you're talking to low-ranking enlisted men is that no one listens to them. So when I showed up they loved having someone to talk to. That's a real privilege for me. The guys on the ground are the guys I care about. I've had the most satisfaction telling their stories. There is trust and there is stuff that you learn to hold back, especially when you're dealing with younger guys or lower ranking officers. That's different from the top brass who are basically just politicians anyway.

Afghanistan would have been difficult enough without Iraq. Iraq made it impossible. The argument that had we just focused on Afghanistan we'd now be okay is persuasive, but it omits the fact that we weren't supposed to get involved in nation-building in Afghanistan.
