Panmunjom

That unprecedented document, the Panmunjom Declaration, set the stage for meetings between Trump and Kim Jong Un, who had until then been slinging insults at one another, with Trump belittling Kim as “little rocket man” and Kim calling Trump a “dotard” — or a senile old person.

It also resumed its nuclear program, rebuilding the nuclear test site it had partially demolished following the Panmunjom Declaration.

He had crossed into that country from South Korea without authorization in July at the border village Panmunjom.

The meeting took place in Panmunjom, the village in the demilitarized zone, or DMZ, where the armistice ending the Korean War was signed decades ago.

But instead of getting on the plane, he left and later joined a civilian tour of the Korean border village of Panmunjom.
