Now remember this is what North Korea admits to (usually after years of denial):
North Korean submarine invades South Korean territory on a commando mission
and then breaks down 37 dead
http://www.cnn.com/WORLD/9612/29/nkorea/The formal apology, carried in English by the North's official Korean Central News Agency and in Korean by Radio Pyongyang, represented a major concession by North Korea.
Pyongyang had insisted its submarine accidentally drifted into South Korean territory during routine training.
South Korea said the submarine was on an espionage mission when it broke down. Thirteen South Korean soldiers and civilians were killed in the massive hunt for the 26 North Koreans who swam ashore.
Twenty-four North Korean commandos were killed or found dead. One was captured alive and another is missing.
North Korea apologizes for kidnapping Japanese civilians
http://www.guardian.co.uk/world/2002/sep/18/japan.northkoreaIt will rank as a stunning confession to one of the most bizarre crimes ever committed by a state. Yesterday, in an extraordinary admission, North Korea's leader Kim Jong-il said his country's special forces abducted at least a dozen Japanese nationals during the 1970s and 80s in a fit of patriotic overzealousness.
Incredibly, the victims of these snatch and grab operations were of no military, scientific or political value. Instead, they included a beautician, a schoolgirl and couples on romantic seaside dates who were suddenly whisked off to the most secretive country on earth.
For years, sensational stories of courting couples being carried off from beaches in the night by North Korean frogmen have filled the Japanese media. At first, few gave much credence to the tales, which seemed to be among the most unlikely of cold war fantasies.
But the rumours persisted and reports of failed abductions and testimonies of captured North Korean spies proved convincing enough for the Japanese government to draw up a list of 11 of its nationals who it suspected were abducted by its reclusive north-east Asian neighbour.
Yesterday, the worst fears were confirmed as Mr Kim ended a decade of denial in an attempt to win economic aid from Japan and remove his country from US president George Bush's "axis of evil".
Now to answer the question why would North Korea do such a thing?
Because last November South Korea had attacked and destroyed a North Korea ship that it thought that had entered its waters. North Korea had demanded but not received an apology.
http://blog.newsweek.com/blogs/declassified/archive/2010/05/21/why-did-north-korea-sink-the-south-korean-ship.aspxAccording to a BBC report, South Korea's ship fired on the North Korean ship after the Northern ship allegedly trespassed across a sea border that the two countries dispute. The North Korean ship returned fire, but not before it had been set ablaze after being hit by South Korean ordnance. North Korea maintained that its ship did not cross the border, and demanded that South Korea apologize, the BBC said. The New York Times reported that a North Korean naval officer had died and that three sailors were injured in the incident.
A tit for tat response from a crazy ass dictator who has a well established history of crazy ass actions. Yep sounds about right.
