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 missilestriking 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.
