WASHINGTON — The Obama administration gave the first explicit signal Tuesday that it might leave no troops in Afghanistan after December 2014, an option that defies the Pentagon’s view that thousands of troops may be needed to keep a lid on Al Qaeda and to strengthen Afghan forces.
‘‘The US does not have an inherent objective of ‘X’ number of troops in Afghanistan,’’ said Ben Rhodes, a White House deputy national security adviser. ‘‘We have an objective of making sure there is no safe haven for Al Qaeda in Afghanistan and making sure that the Afghan government has a security force that is sufficient to ensure the stability of the Afghan government.’’
The United States now has 66,000 troops in Afghanistan, down from a peak of about 100,000 as recently as 2010. The United States and its NATO allies agreed in November 2010 that they would withdraw all their combat troops by the end of 2014, but they have yet to decide what future missions will be necessary and how many troops they would require.
At stake is the risk of Afghanistan’s collapse and a return to the chaos of the 1990s that enabled the Taliban to seize power and provide a haven for Osama bin Laden’s Al Qaeda network. Fewer than 100 Al Qaeda fighters are believed to remain in Afghanistan, although a larger number are just across the border in Pakistani sanctuaries.
Defense Secretary Leon Panetta has said he foresees a need for a US counterterrorism force in Afghanistan beyond 2014, plus a contingent to train Afghan forces. He is believed to favor an option that would keep about 9,000 troops in the country.
Administration officials in recent days have said they are considering a range of options for a residual US troop presence of as few as 3,000 and as many as 15,000, with the number linked to a specific set of military-related missions like hunting down terrorists.
Asked in a conference call with reporters whether zero was an option, Rhodes said, ‘‘That would be an option we would consider.’’
