A powerful U.S. B-52 bomber flew low over South Korea on Sunday, a clear show of force from the United States as a Cold War-style standoff deepened between its ally Seoul and North Korea following Pyongyang's fourth nuclear test, according to AP. North Korea will read the fly-over of a bomber capable of delivering nuclear weapons as a threat. Any hint of America's nuclear power enrages Pyongyang, which links its own pursuit of atomic weapons to what it sees as past nuclear-backed moves by the United States to topple its authoritarian government. The B-52 was joined by South Korean F-15 and U.S. F-16 fighters and returned to its base in Guam after the flight, the U.S. military said.
