During a recent 10-day visit at [Gen. David Petraeus's] invitation, we found a classic, and successful, counterinsurgency campaign being conducted in the south. We drove around Kandahar city and saw markets flourishing. Children who once threw stones at American vehicles now wave at our soldiers. As we went north into the Arghandab River Valley — a Taliban stronghold until a few months ago — we found numerous American and Afghan outposts and soldiers patrolling on foot between them.
We spoke with one company commander who had just returned from a nighttime air assault to secure a village. But Arghandab is growing more secure, and officers are spending more time on governance. Everywhere we went, the message was the same: The Taliban was surprised by the capabilities and ferocity of U.S. forces, and it has largely retreated to regroup.
To be sure, fighting normally slackens in the winter; the extent of recent gains won't be clear until the spring. But when the Taliban returns, it will find many of its old stomping grounds fortified to resist incursions.
