A state department official once told me this about the role of the president. He said: "We wage war for realist reasons, we justify wars for idealist reasons, and it's the president's job to balance the two." I agree.

The fact that our largest presence in the world is our massive military is going to dictate how we engage with the world.

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 want to be the greatest investigative reporter of my generation.

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.

The minute you start arming people in these conflict zones, things don't go as expected. We also need to look at precedent before making these decisions. Instead of listening to Muammar Qaddafi's rhetoric, we should look at how he's behaved. The fact is he's been making concessions recently. He gave up his nuclear weapons. He allowed hundreds of Americans to evacuate Tripoli. Did he crack down on his people who revolted? Yes, but that's not so unusual.

The only thing I've ever regretted is not writing more; not being more honest; not saying how it really is in Baghdad. It's hard to get there sometimes.
