U.S. President Donald Trump said hard to be North Korean leader’s friend.

“Why would Kim Jong-un insult me by calling me "old," when I would NEVER call him "short and fat?” Oh well, I try so hard to be his friend - and maybe someday that will happen!

Earlier the two leaders insulted each other. Speaking during the UN General Assembly, Trump called the North Korean leader “rocket man” who “is on a suicide mission for himself and his regime.” American leader said if North Korea poses threat to the United States, it will be destroyed.

In response, Kin Jong-un called Trump “a frightened dog” and “gangster fond of playing with fire”.
