remind me again who's a threat to the U.S.?

"The warhead of a long-range missile test-fired by North Korea was found in the U.S. state of Alaska, a report to the National Assembly revealed yesterday.

'According to a U.S. document, the last piece of a missile warhead fired by North Korea was found in Alaska,' former Japanese foreign minister Taro Nakayama was quoted as saying in the report. 'Washington, as well as Tokyo, has so far underrated Pyongyang’s missile capabilities.'" - from the KoreaTimes
