Tempting as it would be to pull all Western forces out of Afghanistan soon, the United States should leave some civilian and military advisers behind. Using advisers isn't risk free, but such a strategy could help ensure Afghan stability at a relatively low cost and become a good model for use elsewhere in this age of austerity.

With the rise of endless irregular wars playing out in the shadows, special operations have never been more important to U.S. national security. But policymakers and commanders focus too much on dramatic raids and high-tech drone strikes. They need to pay more attention to an even more important task these forces take on: training foreign troops.

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...

The United States can no longer afford a world-spanning foreign policy. Retrenchment -- cutting military spending, redefining foreign priorities, and shifting more of the defense burden to allies -- is the only sensible course. Luckily, that does not have to spell instability abroad. History shows that pausing to recharge national batteries can renew a dominant power’s international legitimacy.
The military's backward budget process -- driven by parochial service interests rather than White House or Pentagon priorities -- must be fixed, and soon.
Nineteen sixty-nine may be remembered as the year Americans woke up to the importance of an issue that was to be a dominant one in the 1970s. The question of Viet Nam still had the emotional clout. The great ABM debate still captured most of the headlines. But more and more people were beginning to see that bigger and more permanent than both of these was the question of whether America's military spending could be brought under more rational control. In the winter of 1969 it became increasingly clear that we had to find a way to reorient our national priorities so that imperative human needs on the home front were not always being shunted aside because of the claims of "national security." No longer could it be successfully argued that we could afford the needed amounts of "guns and butter." A difficult choice-or at least choices-had to be made, and would have to be made repeatedly, for many years to come.
