I did an embed in Afghanistan on the Pakistan border in 2008. One of the things you realize when you're talking to low-ranking enlisted men is that no one listens to them. So when I showed up they loved having someone to talk to. That's a real privilege for me. The guys on the ground are the guys I care about. I've had the most satisfaction telling their stories. There is trust and there is stuff that you learn to hold back, especially when you're dealing with younger guys or lower ranking officers. That's different from the top brass who are basically just politicians anyway.

I think when war becomes your life, I think its very difficult to have the proper perspective to be able to create a fully balanced policy.

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.

Afghanistan would have been difficult enough without Iraq. Iraq made it impossible. The argument that had we just focused on Afghanistan we'd now be okay is persuasive, but it omits the fact that we weren't supposed to get involved in nation-building in Afghanistan.In my new book, I open with a quote from Donald Rumsfeld. In October 2001, he said of Afghanistan: "It's not a quagmire." Ten years later there are 150,000 Western troops there.

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.

The simple and terrifying reality, forbidden from discussion in America, was that despite spending $600 billion a year on the military, despite having the best fighting force the world had ever known, they were getting their asses kicked by illiterate peasants who made bombs out of manure and wood.

Despite failing to get bin Laden, the U.S. government and media portrayed the early Afghanistan war as a great victory.
