South Korean officials who studied debris from the rocket fired on December 12th have said that it appears North Korea now have the capability to fire rockets to the US West coast, 10,000km away.
“Based on our analysis and simulation, the missile is capable of flying more than 10,000 kilometres with a warhead of 500-600 kilograms,” a South Korean defence ministry official said.
What is still unclear is whether or not North Korea have the technology to allow them to fire a missile capable of surviving re-entry.
