I've always said that if you want to find out what's going on in Iraq or Afghanistan or Libya, I'll give you a choice. You can either read The New York Times, Washington Post, Wall Street Journal, Newsweek, Rolling Stone, or you can go to the NATO, ISAF, multi-national force websites where they have their own news releases. Who will give you a more accurate picture? I'll take the mainstream media.

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.

The general's staff is a handpicked collection of killers, spies, geniuses, patriots, political operators and outright maniacs. There's a former head of British Special Forces, two Navy Seals, an Afghan Special Forces commando, a lawyer, two fighter pilots and at least two dozen combat veterans and counterinsurgency experts. They jokingly refer to themselves as Team America, taking the name from the South Park-esque sendup of military cluelessness, and they pride themselves on their can-do attitude and their disdain for authority.

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.

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 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.

Gore Vidal, Glenn Greenwald, Noam Chomsky, all these guys talk about how the United States became a national security state after World War II. I agree with that thesis. Essentially there's this bipartisan foreign policy elite who've been calling the shots for the last few decades and they're clearly still in control regardless of how clownish or absurd or stupid they demonstrate themselves to be. There's no shaking their orthodoxy.
