Does it?
Feb. 12, 2013
North Korea claimed to have successfully detonated a miniaturized nuclear device at a northeastern test site, state media said, defying U.N. Security Council orders to shut down atomic activity or face more sanctions and international isolation.
South Korea confirmed that the North had indeed carried out the test, and condemned it.
Official North Korean state media said the test was conducted in a safe manner and is aimed at coping with "outrageous" U.S. hostility that "violently" undermines the North's peaceful, sovereign rights to launch satellites. North Korea faced sanctions after a December launch of a rocket the U.N. and Washington called a cover for a banned missile test.
South Korea said earlier Tuesday that the size of the seismic activity indicated a nuclear explosion a bit bigger larger than Pyongyang's two previous tests, of 6-7 kilotons, Reuters notes. The bomb dropped by the U.S. on Hiroshima bomb was around 20 kilotons.
The North said it used a "lighter, miniaturized atomic bomb" that still has more explosive force than devices tested previously.

North Korea said that it had carried out a powerful underground nuclear test -- its second test, which was much larger than one the regime conducted in 2006.
The test was conducted in Kilju, in northeastern North Korea, the South Korean government said. South Korea and the U.S. were said to have been caught off-guard by the test, The New York Times reported at the time.
Analysts cited by the Times believed that this test was meant to be a show of strength during a succession crisis, given that North Korean leader Kim Jong Il was thought to have had a stroke a few months earlier, in August. The test, the North hoped, would ease the transition to Kim Jong Un, by proving the regime's military prowess.
