Pre-nuclear EditBefore the war, North Korea was a powerful nation with a large nuclear arsenal. They had done multiple nuclear tests, which worried the United States and it's president. The President purposed an embargo against North Korea while "the helpless world braces for second blast".
After the terrorist attacks, it was rumored that North Korea had bombed America.
It, along with Iran, was blamed by the leaders of the Allied States of America for the nuclear attacks on the U.S.A as a means of covering their own guilt. North Korea & Iran were then hit by the A.S.A's nuclear missiles & completely destroyed.
