Leaving Afghanistan to the Afghans

In the summer of 2011, I visited the Afghan army's Regional Military Training Center in Helmand Province. The recruits had been there for two weeks, and they looked as strong as any group of U.S. soldiers in basic training. The Afghan drill instructors were as competent, and had the same cocky swagger, as American ones. "Sir, look at all of our volunteers," one drill sergeant proudly said to me. "They're great. We have already won. . . . We just don't know it yet."

To comprehend the United States' progress in Afghanistan, it is important to understand how and where we have focused our resources and what work lies ahead. To be sure, the United States and its coalition partners still have plenty of challenges left to tackle in Afghanistan. However, there are indisputable gains everywhere we have focused our efforts.

In 2009, General Stanley McChrystal, then the commander of U.S. and International Security Assistance Force (ISAF) troops, with the help of David Petraeus, then the commander of the U.S. Central Command, worked hard to design a comprehensive counterinsurgency campaign for Afghanistan that would "get the inputs right," as Petraues often said. The upshot was more resources, troops, and civilian support and better command coherence. There are now more Afghan and coalition soldiers in Helmand and Kandahar Provinces alone than there were in all of Regional Command East, the formation responsible for security in Afghanistan's 14 eastern provinces, when I commanded the latter from 2007 to 2008. As 33,000 U.S. troops begin the drawdown, returning to the United States by next summer, 352,000 Afghan soldiers and police will be in place to continue their work. There are clear signs of progress in Afghanistan, and coalition forces have regained the initiative.

The strategy has worked because it sought to match the coalition's goals with available resources. It involved four major concepts. First, use a bottom-up approach founded on good governance, capable security forces, and engagement with local communities. If towns had good leaders and security providers, populations would find local solutions to their local problems, with just a little help from Kabul. Insurgents could no longer exploit popular grievances about security, justice, and a lack of basic services...
