A defaced portrait of North Korea leader Kim Jong-un is seen during a rally against North Korea's nuclear test near the U.S. embassy in central Seoul February 12, 2013. North Korea conducted its third nuclear test on Tuesday in defiance of U.N. resolutions, angering the United States and Japan and prompting its only major ally, China, to call for calm. The placards read, "Crazy dog needs to be beaten down!" (R) and "Bomb North Korea's nuclear test!"
