In a special session of Congress, the United States begins the second Korean war. The President of South Korea was injured during the attack on Seoul, so the Vice President, who was out of the city when the strike started, takes over the post while he recuperates. He meets with President Bush at the White House to discuss their plans for war.
I'm sorry to nitpick, but South Korea doesn't have a vice president. Just swap "Vice President" with "Prime Minister" (he's first in line behind the president).
