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.
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.
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.
Even on just the career level for your average officer, there's no incentive to end the wars. There's not even an incentive for these think-tank guys to end the wars. They would never admit it and say, "Oh, how could we at the Center for a New American Security not want the wars to end?" Well then, why the hell are you continuing to promote strategies that will keep us fighting for years?
