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.

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.

The military sensed weakness, exploited it and played Barack Obama. Obama's foreign policy has been consistently hawkish despite this reluctant warrior schtick that he pulls. But at the end of the day a reluctant warrior is still a warrior. Look at the drone strikes, the tripling of the war in Afghanistan, and now Libya. I'm convinced that had Obama been in the Senate in 2003 he would have voted for the Iraq war. He's clearly easily convinced by his advisers and the Pentagon.

The humanitarian argument is so selective I find it difficult to swallow. It's not even so much about the choice as to where we should get involved and where we shouldn't. The minute you start arming people in these conflict zones, like Iraq and Afghanistan, things don't go as expected.

I made this bad joke on Twitter saying, "I want to put in my first no-bid contract to train the Libyan army and police force." These counter-insurgency guys like to say, "We don't do the big F-16 or big boondoggle projects, we're not pulling this stuff because it's good business." But in fact it turns out there are tons of business opportunities involving counter-insurgency operations - and it's not like we're getting rid of the boondoggle programs either, we're just doing more of everything.

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.

It was interesting watching the Afghanistan war review deliberations, this three-month process where Barack Obama did the most thorough foreign policy review ever by a modern American president. Compare that to Libya. For a month he said we weren't going to do anything, then suddenly changed his mind and did it on the fly. My view is that it's not how long or quick you take to make a decision, it's whether you make the right one.
