Nice port Thanks for Info but I think It's dust in the eyes NK would never attack US or any other country reason being it will get a total devastating response. US is NK threat as a mean to put in air defenses and other military hardware in South Korea and Japan to contain Russia and China, resteemed!
Unfortunately the threats are enough to put people on edge to the point where they might do something stupid. Asia already has problems massive problems with land claims and they could be the straw that breaks the camel's back.
