Trump, with his bombastic, childish bluster, has painted himself into a corner.  Where do you go when you promise action if you are threatened, then are threatened again and nothing happens?  Trump fails to understand that kim, like trump, only makes the threats to appear strong to his own people.  He will never attempt a first strike because he knows he is toast if he does.  If trump was more mature, he would ignore the threats and concentrate on rallying the world to make sanctions more effective.  However, being thin-skinned and narcissistic, he responds like a spoiled toddler being told "no."  Meanwhile, the war mongers who advocate military action also fail to understand the consequences of military action.  Sure, in the end, the destruction of north korea is assured, but how many thousands, or millions, of people will be killed to satisfy those impatient idiots?
