Is the Afghan army just a figment of Washington's imagination?

The big Afghanistan debate in Washington is not over whether more troops are needed, but just who they should be: Americans or Afghans -- Us or Them. Having just spent time in Afghanistan seeing how things stand, I wouldn't bet on Them. Frankly, I wouldn't bet on Us either. In eight years, American troops have worn out their welcome. Their very presence now incites opposition, but that's another story. It's Them -- the Afghans -- I want to talk about. Afghans are Afghans. They have their own history, their own culture, their own habitual ways of thinking and behaving, all complicated by a modern experience of decades of war, displacement, abject poverty, and incessant meddling by foreign governments near and far -- of which the United States has been the most powerful and persistent. Afghans do not think or act like Americans. Yet Americans in power refuse to grasp that inconvenient point.
