Secretary of State Hillary Clinton said North Korea may soon be back on a list of state sponsors of terrorism after their nuclear test. "We're going to look at it. There's a process for it. Obviously we would want to see recent evidence of their support for international terrorism," Clinton said Sunday on This Week with George Stephanopoulos. North Korea was removed from the terror list in October to foster denuclearization talks, and benefited from the lifting of some trade sanctions. But since the impoverished nation detonated a test bomb May 25, countries that were reluctant to condemn North Korea such as China and Russia will sign on to strong sanctions against them. North Korea is also using two captured female U.S. journalists as a bargaining chip with the U.S, analysts say.
