FILE - In this Dec. 12, 2012 file photo released by Korean Central News Agency, North Korea's Unha-3 rocket lifts off from the Sohae launch pad in Tongchang-ri, North Korea. After three nuclear tests of apparently increasing power and a long-range rocket launch that puts it a big step closer to having a missile that can carry a nuclear warhead to American shores, many believe that, in a matter of years - as little as five, maybe, though the timeframe is a point of debate - Pyongyang will have a very scary nuclear arsenal. Though it's a view not embraced by everyone, one respected South Korean expert says North Korea could be working toward 80 to 100 nuclear-tipped missiles. (AP Photo/KCNA, File) less
