19 March 2013A North Korean military progaganda video posted online shows the White House and the US Capitol building being hit in a missile attack.The video on the semi-official Uriminzokkiri website shows North Korea's military might on parade before a target appears on America's government buildings."The White House is caught by our sighting device. The inner citadel is within our striking range of an atomic bomb," subtitles for the video said.The North has threatened a nuclear war with the United States in response to new United Nations sanctions over its latest nuclear test.It also has also vowed to strike back at South Korea and the US for conducting joint military drills, which they see as rehearsals for war.US B-52 bombers today participated in the ongoing joint military drill, Foal Eagle, to demonstrate a strong alliance between the two countries in the face of North Korea's threats.Foal Eagle is an annual drill that runs between March 1 and April 30.US Defence Secretary Chuck Hagel said on Saturday the country planned to deploy 14 additional anti-missile interceptors in response to a growing nuclear threat from North Korea.Although experts say the North is still years away from being able to hit the continental US with a nuclear weapon, rhetoric from its leaders has increased in recent weeks.Earlier this month the North announced it would no longer adhere to the 1953 armistice that ended the war on the Korean peninsula.
