I had a recurring fantasy in which I took (Rudy Giuliani) out during a press conference (it was nonlethal, just something that put him out of commission for a year or so), saving America from the horror of a President Giuliani. If that sounds like I had some trouble being 'objective,' I did.

If the thumbnail version of the Iraq war was that Bush lied about WMD, the thumbnail version of Obama's war in Afghanistan is that the generals pushed him into a war he didn't want to fight.

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.

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.

During the invasion of Iraq in 2003, the military conducted only a handful of drone missions.

The humanitarian argument is so selective I find it difficult to swallow. It's not even so much about the choice as to where we should get involved and where we shouldn't. The minute you start arming people in these conflict zones, like Iraq and Afghanistan, things don't go as expected.
