Folks...President Trump and his "button that works" will meet "little rocketman" to discuss the North Korean construction of nuclear weaponry capable of poisoning Earth for a 100,000 years in all directions.
While Kim Jung Un was too little(think young) to know about it...and...perhaps...has never heard of it...for everyone else...CHERNOBYL* was the finale of nuclear weapon development.
When that radioactive cloud spread across Europe and on into Canada and the greater northwest of America...the world realized nucealr weapons had to be banned lest CHERNOBYL be repeated a thousand times and all life doomed.
*Chernobyl was a nuclear power plant with nuclear power in its rawest format. The safety equipment failed due operator error and the reactors melted spewing a radioactive plume that is still causing horrible brith defects in the Ukraine and Sweden.
