Though Obama’s goals were not altogether clear, they might be stated as follows:
Deny al Qaeda a base in Afghanistan.
Create an exit strategy from Afghanistan similar to the one in Iraq by creating the conditions for negotiating with the Taliban; make denying al Qaeda a base a condition for the resulting ruling coalition.
Begin withdrawal by 2011.
To do this, there would be three steps:
Increase the number and aggressiveness of U.S. forces in Afghanistan.
Create Afghan security forces under the current government to take over from the Americans.
Increase pressure on the Taliban by driving a wedge between them and the population and creating intra-insurgent rifts via effective counterinsurgency tactics.
In analyzing this strategy, there is an obvious issue: While al Qaeda was based in Afghanistan in 2001, Afghanistan is no longer its primary base of operations. The group has shifted to Pakistan, Yemen, Somalia and other countries. As al Qaeda is thus not dependent on any one country for its operational base, denying it bases in Afghanistan does not address the reality of its dispersion. Securing Afghanistan, in other words, is no longer the solution to al Qaeda.
