Kim is no crazier than Trump (a low bar).  The U.S. can't just go around nuking other countries.  You have to understand how close everything is there.  You are talking about killing hundreds of thousands of people in S. Korea and thousands of Americans in SK (and millions in NK) like it was some video game.

We've lived with Russia and China having nuclear weapons for 70 and 50 years.  What's the hurry to go to war?  Sure Kim is a crazy despot. But he is not going to USE his nukes unless we attack him because he knows that is game over.

His nukes are designed to DETER an attack by the U.S.   If the U.S. attacks, that TRIGGERS the use of nukes.

I am surprised after the disasters that we have created by attacking Mideast countries that you would advocate yet another invasion of a country who may be talking tough (and Trump isn't???) but which has made no move against us for almost 70 years.
