His tongue firmly in cheek, President Trump on Saturday tweeted a question to the leader of North Korea: “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!” the president tweeted from Hanoi.

The gibe followed a day in which North Korea lobbed rhetorical bombs at Trump, calling him a “warmonger” and charging his trip to Asia was designed “for confrontation.”

An earlier statement from the hermit kingdom’s foreign ministry said, “Reckless remarks by a dotard like Trump will never scare us or put a stop to our advance.”

It claimed Trump’s trip has pushed North Korea “to speed up the effort to complete our nuclear force.”
