North Korea confirms H-bomb test

SEOUL, South Korea

North Korea said Wednesday it had conducted a hydrogen bomb test, a defiant and surprising move that, if confirmed, would put Pyongyang a big step closer toward improving its still-limited nuclear arsenal.

A television anchor read a typically propaganda-heavy statement on state TV that said North Korea had tested a “miniaturized” hydrogen bomb, elevating the country’s “nuclear might to the next level” and providing it with a weapon to defend against the U.S. and its other enemies.

The statement said the test was a “perfect success.”

The test, if confirmed by outside experts, will lead to a strong push for new, tougher sanctions at the United Nations and further worsen already abysmal relations between Pyongyang and its neighbors.

North Korean nuclear tests worry Washington and others because each new blast is seen as pushing North Korea’s scientists and engineers closer to their goal of an arsenal of nuclear-tipped missiles that can reach the U.S.

While a hydrogen bomb is much more powerful than an atomic bomb, it is also much harder to make. In a hydrogen bomb, radiation from a nuclear fission explosion sets off a fusion reaction responsible for a powerful blast and radioactivity.

North Korea is thought to have a handful of rudimentary nuclear bombs and has spent decades trying to perfect a multistage, long-range missile to eventually carry smaller versions of those bombs. After several failures, it put its first satellite into space with a long-range rocket launched in December 2012.
