The world have 8 nuclear weapon powers - U.S., Russia, China, UK, France, India, Pakistan, Israel. North Korea is not it. Far from it. So is Iran. 

Of these there is only one madman with his finger tips on the Red Launch Nuke Button. Smiling, eager. He alone among leaders have this power, not requiring Congressional approval. All others require parliamentary approval for war, then approval for nuclear weapons use. 

Donald Trump

This madman and his war machine is a danger to mankind. Not KimJ.
