U.S. Navy Prepares to defend allies

Off the coast of the Korean Peninsula, U.S. and South Korean Navy ships prepared for an event they hope will never happen: a North Korean land and air attack against their neighbors to the south. As for the 5,000 sailors on board the Reagan, they hope their mere presence off the Korean Peninsula can deter a North Korean strike that would surely escalate to war.
