March 21, 2013 North Korea Threatens U.S. Bases in Japan After B-52 Flight ------------------------------------------------------------ North Korea has threatened a new attack on the U.S. military over its ongoing training drills with South Korea. Earlier today, the North Korean regime said it could hit U.S. military bases in Japan after the United States flew nuclear-equipped B-52 bombers. North Korea called the B-52 flight an "unpardonable provocation." It was the latest in a series of threats from North Korea following passage of a U.S.-backed Security Council resolution earlier this month in response to North Korea's most recent nuclear test. .
