It is ever clearer that Trump has made up his mind. If he turns his threat into reality and totally destroys the DPRK, that's 25,000,000 lives extinguished at the click of a button.
Of course, the DPRK will respond, if they can. Another 25,000,000 live in the Seoul Capital area; Kim could throw a nuke and extinguish them. 30,000 American troops along the DMZ: gone. That's over 50,000,000 people. 41,000,000 were killed in four years in World War I.
If Kim is able to get another nuclear missile off and it hit Japan, if it killed 10% there, we're in uncharted territory. 12,000,000 more killed, a total of 62,000,000, more than were killed in four years of World War II.
If he can launch an ICBM, who knows if he has the capability to reach Los Angeles? Ten percent there is 1,800,000.
2,000,000 were killed during the Korean War. Since armistice, 64 years ago, number of U.S. and South Korean troops killed: 130.
Kim and Trump have made up their minds.
