Despite warnings to from the international community to stop, North Korea tested the most powerful ICBM to date last night. The hermit kingdom launched yet another Intercontinental Ballistic Missile (ICBM) which splashed down in the sea off the coast of Japan.

Kim Jong Un issued a handwritten order for the launch that said:

 "I order a test launch. Carry out on Nov 29 at dawn. Fire it bravely for the Party and the motherland!"

North Korea seems pleased as punch about the launch, stating that their nuclear state is "complete":

Pyongyang said in a statement Wednesday local time that the missile flew for 53 minutes before landing in "targeted waters" in the East Sea of Korea and that the missile can be tipped with a "super-large heavy warhead.

"[North Korean leader] Kim Jong Un declared with pride that now we have finally realized the great historic cause of completing the state nuclear force, the cause of building a rocket power," North Korea said. (source)

What we learned can help us to be better prepared, should things escalate beyond tests.

They can definitely hit any part of the United States

There has been a lot of supposition with previous tests, like the one last July, when it was determined by some experts that they could strike into the US as far as Chicago.  But last night, by the time the missile had splashed down in waters of the Japanese economic zone, General Mattis, the Secretary of Defense warned that they'd proven they "could threaten everywhere in the world."
