After the initial assault that drove al Qaida to Pakistan and the Taliban rulers from power, it has never been clear what U.S. troops were supposed to accomplish. Were they hunting down terrorists (but the bad guys had decamped) or propping up a government (the one in Kabul seldom seemed to control little more than the capital, if that) or installing good governance (Afghanistan remains one of the most corrupt countries in the world) or training a local army (after nearly ten years the Afghan army has only 600 soldiers thought ready to fight)? Who knows? All the war has been good for has been killing Afghans, U.S. soldiers, and allied NATO troops. Oh, any enriching military contracting companies.
The Obama administration is dragging its heals about getting out. They clearly know and intend that the U.S. will leave. But they proceed by baby steps.
There is no reason for more killing in Afghanistan by our troops and no reason to continue to waste the lives of our forces. That unfortunate country needs to heal itself and run its own affairs. Enough is enough.
