PYONGYANG, North Korea, March 26 (UPI) -- North Korea's newest propaganda video, "Last Chance," shows a nuclear strike on Washington, D.C., and warns the United States against provoking an attack.
The four-minute video, uploaded Saturday to the North's propaganda website DPRK, includes a computer-generated scene of a submarine-launched nuclear missile striking the Capitol building in Washington, D.C.
As the weapon is shown exploding near the Lincoln Memorial, Korean subtitles appear on the screen.
"If the American imperialists provoke us a bit, we will not hesitate to slap them with a pre-emptive nuclear strike," the message said
The video also shows images from the Korean war and the 1968 capture of the U.S. Navy spy ship, the Pueblo. It includes other "humiliating defeats" in the history of U.S.-North Korea relations.
Tokyo's National Institute for Defense Studies also reported on Friday North Korea has been ramping up submarine-launched ballistic missile development and may have miniaturized nuclear weapons.
