The massacre of 16 Afghan villagers, allegedly by a U.S. soldier, has raised tensions between the United States and the Afghan government.  Afghan President Hamid Karzai demanded troops withdraw from villages and return to their bases following the March 11 shooting and he is asking the NATO-led International Security Assistance Force to hand over security responsibility to Afghan forces a year earlier than planned.

Retired Maj. Gen. James A. "Spider" Marks, a former commander of the U.S. Army Intelligence Center, says that if U.S. troops are not allowed into villages, then officials may decide to bring them home.
