Trump took some time out of his busy schedule of insulting black athletes to inflame the tensions with North Korea…

Aides warned Trump not to attack North Korea’s leader personally before his fiery U.N. address

Senior aides to President Trump repeatedly warned him not to deliver a personal attack on North Korea’s leader at the United Nations this week, saying insulting the young despot in such a prominent venue could irreparably escalate tensions and shut off any chance for negotiations to defuse the nuclear crisis.

Trump’s derisive description of Kim Jong Un as “Rocket Man” on “a suicide mission” and his threat to “totally destroy” North Korea were not in a speech draft that several senior officials reviewed and vetted Monday, the day before Trump gave his first address to the U.N. General Assembly, two U.S. officials said.

Some of Trump’s top aides, including national security advisor H.R. McMaster, had argued for months against making the attacks on North Korea’s leader personal, warning it could backfire.

But Trump, who relishes belittling his rivals and enemies with crude nicknames, felt compelled to make a dramatic splash in the global forum.

Some advisors now worry that the escalating war of words has pushed the impasse with North Korea into a new and dangerous phase that threatens to derail the months-long effort to squeeze Pyongyang’s economy through sanctions to force Kim to the negotiating table.

A detailed CIA psychological profile of Kim, who is in his early 30s and took power in late 2011, assesses that Kim has a massive ego and reacts harshly and sometimes lethally to insults and perceived slights.

It also says that the dynastic leader — Kim is the grandson of the communist country’s founder, Kim Il Sung, and son of its next leader, Kim Jong Il — views himself as inseparable from the North Korean state.

As predicted, Kim took Trump’s jibes personally and especially chafed at the fact that Trump mocked him in front of 200 presidents, prime ministers, monarchs and diplomats at the U.N.

Kim volleyed insults back at Trump in an unprecedented personal statement Thursday, calling Trump “a mentally deranged U.S. dotard” and a “gangster” who had to be tamed “with fire.”

Kim’s foreign minister, Ri Yong Ho, threatened to respond with “the most powerful detonation,” a hydrogen bomb test in the Pacific Ocean, according to South Korea’s Yonhap News Agency.
