Apparently, they're going to send a satellite to space. Right over Japan.
"North Korea has given international agencies notice of the rocket's planned trajectory that would take it over Japan, dropping booster stages to its east and west."
And the U.N is suspecting it's for launching missiles
"Regional powers see the launch as a disguised test of its longest-range missile and a violation of U.N. sanctions forbidding the reclusive state from firing ballistic missiles."
And Japan is fucking pissed
"Japan may deploy two Aegis-equipped destroyers, capable of shooting down missiles, to waters between North Korea and Japan, Japanese media have said. The United States also has naval ships deployed in Asia that can intercept missiles.
North Korea doesn't care.
"North Korea has said shooting down the rocket would be an act of war."
