KimJ is wrong calling Trump 'deranged'. Trump huffing, puffing, barking, screaming, insulting, threatening extermination is not deranged. It is 'normal'. 

Imagine any other leaders of the world - Xi of China, Putin of Russia, Modi of India, Merkel of Germany, Trudeau of Canada, etc. goes to the UN General Assembly and declares what Trump did - destroy an entire country. Did Xi and Putin, both neighbors of DPRK, huff and puff? You can understand why these leaders absolutely will not be in the same room as Trump. The last leader who did as Trump did was none other than Adolf Hitler - against the USSR. 

But why is Trump, a guy who cares only about money and fame, know zilch about global politics and economics, suddenly want to 'totally destroy' a country of 25 millions he knows nothing about? 1. He has been cornered and has no military options. Very bad for the war empire. 2. What's at stake is not the U.S. itself. Is the empire most prized colonial possessions Japan and S. Korea.
