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.

An information operations team was sent to Afghanistan to conduct various psychological operations on the Afghans and Taliban. The team was then asked not to focus on the Taliban but on manipulating senators into giving more funds and troops [to the war].

And 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.

The fact that our largest presence in the world is our massive military is going to dictate how we engage with the world.

The way the Pentagon and its defenders have pushed back against this story is to say: "They weren't doing psychological operations, they were doing information operations and public affairs. They were just helping us spin senators like we normally do."

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.

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.
