Kim ain’t Bagdhad Bob. The truth is there are and have been many men who would just as soon see the world burn. A good example is those who flew the planes into the towers.
The problem is you are trying to use logic to explain the actions of a mad man.
Many? BS. And Kim is not suicidal anymore than any other tin horn dictator who wants to stay in power. I include the mullahs of Tehran in that equation.
