Earlier this week at the UN, Trump said he would "destroy" North Korea.
Kim Jung Un responded by calling the president a “mentally deranged U.S. dotard” and describing his UN speech as “unprecedented rude nonsense.” (By the way, I had to look it up. A dotard is an old person, especially one who has become weak or senile.) He also said: "A frightened dog barks louder."
Trump responded by calling Kim a “madman” whose regime will be “tested like never before”.
These are the "grownups" who may decide if we live or die. Sleep tight.
