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.

Inside the White House there were always extreme amounts of doubt about whether they should be escalating in Afghanistan. In fact, most of the president's advisers said, "This is probably not going to work." A lot of people in the military said, "This is probably not going to work."

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.

A new software is being developed so the psychological operations guys and the Pentagon's strategic communications guys - and we don't really know who's running it - but this is all totally out in the open. It's this new program that will allow them to have like ten fake Twitter accounts and ten Facebook accounts so you can pretend.

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.

Look, I went into journalism to do journalism, not advertising.
