This is North Korea's retaliation after the U.S. flew B-2 spirit bombers over South Korea in military training exercises. The stealth bombers flew over 6,500 miles from Whiteman Air Force Base in Missouri and dropped bombs on a South Korean range. 

North Korea's state-run news agency KCNA reported that Kim Jong-un had a meeting with top generals on Friday morning and signed off on the plan. KCNA also reported that he "said he has judged the time has come to settle accounts with the U.S. imperialists in view of the prevailing situation."

"We will be prepared, we have to be prepared, to deal with any eventuality," said Defense Secretary Chuck Hagel. "We must make clear that these provocations by the North are taken by us very seriously and we'll respond to that. I think their very provocative actions and belligerent tone has ratcheted up the danger."

North Korea and U.S. tensions have risen in the past months, as North Korea launched a long-range rocket and tested its third nuclear bomb. These threats by Jong-un will only increase the tensions more.
