U.S. President Barack Obama has asked his military and civilian advisers for more options on sending additional troops to Afghanistan, sources say.

Citing unnamed administration officials, The Washington Post reported a 90-minute meeting with the U.S. Joint Chiefs of Staff Friday at the White House ended with a presidential demand for additional choices on Afghanistan troop levels, including one that would send fewer than the 40,000 fresh troops being sought by Gen. Stanley McChrystal, the commander of U.S. forces in Afghanistan.

The newspaper said Obama has requested another such meeting before he makes a decision on troop levels. His national security team is said to be divided on the issue and the president appears to be seeking a compromise solution that would appeal to both his military and civilian advisers, the sources said.

The Post quoted the advisers as saying Obama has yet to decide between a counterinsurgency strategy requiring large numbers of troops to protect Afghan cities or a counterterrorism strategy with fewer troops. The president, they say, is considering a way to blend the two strategic visions for different parts of the country.
