When you go into a country like Libya where a large chunk of the population wants the old regime back you could end up with a protracted civil war. That we're now in a stalemate was both entirely predictable, and predicted. That we're now relying on drones is disturbing. How vital can a cause be if we're not willing to risk American lives to defend it, and instead use robots and remote control operators? It gets me back to the larger feeling about the intervention - there's just not a compelling reason for us to be involved.

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.

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.

I've always said that if you want to find out what's going on in Iraq or Afghanistan or Libya, I'll give you a choice. You can either read The New York Times, Washington Post, Wall Street Journal, Newsweek, Rolling Stone, or you can go to the NATO, ISAF, multi-national force websites where they have their own news releases. Who will give you a more accurate picture? I'll take the mainstream media.

A soldier in Iraq said that he wanted to "punch Donald Rumsfeld in the gut, then in the face" or something like that. He wanted me to use his name, but I knew he'd get in trouble, so I didn't. However, I felt it was a great quote because it summed up the frustration of those guys at that moment.

Johnny Apple, a New York Times correspondent, wrote a front-page story saying Afghanistan could be a quagmire and he was mocked and derided. What is certainly true is that all sorts of resources that would have been used in Afghanistan were diverted to Iraq. Would those resources have helped? Almost undoubtedly. Whether or not Afghanistan would be a peaceful nation-state had we not gone into Iraq I doubt. Afghanistan is going to be Afghanistan, no matter how hard we try to make it something else.

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.
