According to information from the Swedish Armed Forces, this brusque message was first conveyed in a North Korean radio broadcast, then printed as an official document and distributed to the United Nations.Don't mess with Sweden. Their military is in excellent shape (maybe 'cause they don't use it?)
The North Koreans' attack is not directed against the Swedish government as such, but against Sweden's and other neutral countries' military observation missions on the border between North and South Korea.
Sweden is active in the Neutral Nations Supervisory Commission (NNSC) present in the area. Following the end of the Korean War in 1953, the NNSC's task is to keep the peace with the help of the Swedes and the Swiss in demilitarized zones. - The Local (Sweden News In English)
