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.

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.

The idea of aerial military surveillance dates back to the Civil War, when both the Union and the Confederacy used hot-air balloons to spy on the other side, tracking troop movements and helping to direct artillery fire.

By the time of Andi Parhamovich death, I had already grown skeptical of the Iraq war. What her death made me realize was what the actual price was. Going through that kind of loss and seeing how devastating it was on her family and friends made me decide that I was only going to write about things that I really believed in. I'm not going to compromise on that.

The guys on the ground are the guys I care about. I've had the most satisfaction telling their stories. But when you're in combat with somebody, yes, a bond does grow.

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.

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.
