In late 2006 and early 2007, the Bush administration recognized that Afghanistan was deteriorating sharply and undertook a series of strategy reviews. The reviews led to more troops and a new counterinsurgency strategy with attention to training Afghan security forces and improving governance, reconstruction, and counternarcotics. As in 2003, the new approach ran into the buzzsaw of bureaucracy, the fog and friction of war, unanticipated challenges, and, now, a far stronger and more resilient enemy. The problems with the American war effort in 2007 and 2008 were less problems of strategy than of implementation. Having blundered badly in the early years and created huge problems for itself, the American effort was now playing catch up, trying to adjust rapidly to a deteriorating situation.
