War Downsized

How to Accomplish More With Less

The United States, facing deepening economic and fiscal woes at home, is preparing to withdraw from Afghanistan. More and more policymakers, congressional representatives, and members of the public are calling for the majority of U.S. forces to pull out as quickly as possible and for Washington to shift from an expensive counterinsurgency strategy, in which tens of thousands of U.S. and NATO troops protect the Afghan population, to a cheaper counterterrorism strategy, in which special operations forces strike at terrorist leaders in Afghanistan and Pakistan and the Afghans are left largely on their own.

The counterinsurgency strategy began in earnest in 2009, when the United States raised its total number of troops in Afghanistan to nearly 100,000. This Afghan surge led to tactical success: Kandahar and Helmand were largely secured, and the number of Afghan police and army soldiers nearly doubled. But it was expensive. In 2011, the U.S. Congress authorized nearly $114 billion for the effort, roughly a fourth of the entire cost of the Afghan war since 2001. Given the current economic climate, such high annual outlays are no longer sustainable. Last June, U.S. President Barack Obama announced that 33,000 American troops will leave Afghanistan by the end of 2012 and that Afghan forces will take the lead in the country's security by the end of 2014. Although it remains undecided exactly how fast the withdrawal will proceed after 2012 and what sort of U.S. presence will remain after 2014, Washington is facing strong domestic pressure to bring its troops home and to focus on rebuilding the economy.

At first glance, shifting to counterterrorism would seem the best way to meet this goal. A counterterrorism approach would cut costs by pulling out most U.S. ground troops. Special operations forces would remain in the larger bases, with responsibility for launching missions to kill or capture al Qaeda members, high-level Taliban figures, and leaders of the Haqqani network. What is more, the U.S. Navy SEAL raid that killed Osama bin Laden last May seemed to give this approach credibility by suggesting that knocking out al Qaeda -- the primary reason why the United States entered Afghanistan in the first place -- does not require tens of thousands of U.S. troops.
