What is the big deal if North Korea successfully launched an ICBM?
North Korean ICBM
An Inter-Continental Ballistic missile ICBM, is different from any other missiles because of the range. They reach 5,600 km. If a state have one, they can hit targets far beyond its borders. Furthermore, ICBMs are mostly used to lift nuclear warheads. Once they reach space they launch multiple nuclear warheads which are impossible to counter. The US Air Force has been developing a technology to track and hit ICBMs post launch. If it is true that North Korea successfully launch an ICBM today, then we are entering a new phase in how the world deals with the rogue nation. Only the United States, Russia and China possess ICBMs.
