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 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.

General McChrystal wanted to be on the cover of Rolling Stone.

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.

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."

I'm talking to people all of the time. So it hasn't really had a big impact. Access is never my main concern anyway. If you keep digging and making phone calls you can get stories and not have to rely on the good graces of the Pentagon spokesperson. I am not in his good graces.

The guys on the ground are the guys I care about. I've had the most satisfaction telling their stories. But when you're in combat with somebody, yes, a bond does grow.
