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.

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.

After a decade of war you have this Pentagon-military apparatus run amok using resources that they shouldn't be to try to manipulate U.S. public opinion.

Despite failing to get bin Laden, the U.S. government and media portrayed the early Afghanistan war as a great victory.

I'm post-cynical on this stuff. I look at the El Salvador model as the glory days: Why don't we just fund the death squads secretly and keep our boys at home? That where I almost am at this point. Clearly the American military has been a force for good for the United States. There's a reason we have a standing military. But there's something to be said for having a much smaller military because then we wouldn't be tempted to get involved in things we shouldn't be getting involved in.

Gore Vidal, Glenn Greenwald, Noam Chomsky, talk about how the U.S. became a national security state after World War II. Essentially there's this bipartisan foreign policy elite who've been calling the shots for the last few decades and they're clearly still in control regardless of how clownish or absurd they demonstrate themselves to be. There's no shaking their orthodoxy. To me it was the most depressing thing, these full-scale military interventions firsthand for a number of years, seeing how quickly we can get involved in another war with very little debate.

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.
