Speaking to about 2,000 U.S. and allied troops at the major U.S. base in Afghanistan, Obama said, "Those folks back home are relying on you."
"I know it's not easy," he said. "You're far away from home. You miss your kids, you miss your spouses, your family, your friends." But he added, "If I thought for a minute that America's vital interests were not served, were not at stake here in Afghanistan, I would order all of you home right away."
