I'm post-cynical on this stuff. I look at the El Salvador model as the glory days: Why don't we just fund the death squads secretly and keep our boys at home? That where I almost am at this point. Clearly the American military has been a force for good for the United States. There's a reason we have a standing military. But there's something to be said for having a much smaller military because then we wouldn't be tempted to get involved in things we shouldn't be getting involved in.

Gore Vidal, Glenn Greenwald, Noam Chomsky, talk about how the U.S. became a national security state after World War II. 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 they demonstrate themselves to be. There's no shaking their orthodoxy. To me it was the most depressing thing, these full-scale military interventions firsthand for a number of years, seeing how quickly we can get involved in another war with very little debate.

A woman I loved [Andi Parhamovich] was killed in Baghdad in January 2007 – al-Qaeda in Iraq took credit for it … The memorial service with me crying over an empty coffin.

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.

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.

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.

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.
