The military is considering the deployment of up to 20,000 additional U.S. Marines to Afghanistan. The surge would come as a similar number of troops is cut from Iraq, meaning the Marines would still comply with their seven-month deployment schedule. The U.S. now has 34,000 troops in Afghanistan and just 2,200 Marines. "The time is right for Marines in general terms to leave Iraq. It's very much a nation-building kind of environment that's taking place there," the Marine Corps Commandant explained.
