what is a ballistic missile and what does it do
Ballistic missile A ballistic missile follows a ballistic trajectory to deliver one or more warheads on a predetermined target. These weapons are only guided during relatively brief periods of flightâ€”most of their trajectory is unpowered, being governed by gravity and air resistance if in the atmosphere. Shorter range ballistic missiles stay within the Earth's atmosphere, while longer-ranged intercontinental ballistic missiles (ICBMs), are launched on a sub-orbital flight trajectory and spend most of their flight out of the atmosphere
North Korea–United States relations North Korea–United States relations (Chosŏn'gŭl: 북미관계; Hancha: 北美關係; RR: Bugmi gwangye) are hostile and developed primarily during the Korean War. In recent years relations have been largely defined by North Korea's six tests of nuclear weapons, its development of long-range missiles capable of striking targets thousands of miles away, and its ongoing threats to strike the United States[1] and South Korea with nuclear weapons and conventional forces. During his presidency, George W. Bush referred to North Korea as part of "the axis of evil" because of the threat of its nuclear capabilities.[2][3]
