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.

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.

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.

One of their major initiatives was getting all officers on Facebook. So the question is, why are these people who are there to train the Afghans being pressured to be on Facebook? Again, it sounds benign until you realize that the military's concern isn't the Afghans, it's convincing the American people that we should be in Afghanistan.Soldiers can put up pictures and say "See how happy the Afghans are because of our presence here." It's a way to directly influence the American people using propaganda.

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.

The frightening aspect is that it's part of a larger effort from the Pentagon to tear down the wall between public affairs and propaganda, and essentially say there is no difference between information operations, public affairs and psychological operations. They have a new name for that too, it's called Information Engagement. What I hope people take away from this is that it's a window into a larger phenomenon. After a decade of Iraq war you have this Pentagon-military apparatus run amok using resources that they shouldn't be to try to manipulate U.S. public opinion.

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." If the thumbnail version of the Iraq war was that George W.Bush lied about mass destruction weapons, the thumbnail version of Barack Obama's war in Afghanistan is that the generals pushed him into a war he didn't want to fight.
