North Korea has moved a missile into position for launch, and CNN's Tom Foreman walks us through how the situation could escalate.
Military intelligence says the missile has been moved into position somewhere along a 250-mile stretch along the country's eastern coast. We do not know where the missile is, but U.S. intelligence is fairly certain of what kind of weapon it is, likely a bare bones-type of missile called a Musadan, believed to have evolved from a type of Russian submarine missile. The Iranians, who trade arms with the North Koreans, are also believed to have these.
Musadan missiles are believed to be reliable, but vary in size, measuring anywhere from 39 to 62 feet in length. It can carry a payload, essentially a bomb, of 2.6 tons. The missile is either a nuclear warhead, which is unlikely given North Korea's nuclear program, or a high explosive warhead.
