Gen. Casey Says More U.S. Troops Needed in Afghanistan
Casey says more troops would help cut into the Taliban's successes while U.S. forces continue training Afghan security forces.
President Barack Obama is considering several options to increase the number of troops fighting in Afghanistan, including Gen. Stanley McChrystal's preference of about 40,000 additional U.S. forces next year.
Casey appeared Sunday on NBC's "Meet the Press."
He also said the Army is taking a hard look at itself to make certain that something like the Fort Hood rampage doesn't happen again.
The shootings left 13 dead and 29 wounded. The alleged gunman, Maj. Nidal Malik Hasan, was wounded by civilian police.
Casey on Sunday warned against reaching conclusions about motives until investigators have fully explored the attack. Early reports suggest Hasan, a Muslim, was angry about the wars in Afghanistan and Iraq and worried about his pending deployment to Afghanistan.
Casey says focusing on Hasan's Islamic roots could "heighten the backlash" against all Muslims in the military.
