Donald John Trump’s surprise announcement of a planned meeting with Kim Jong Un underscores arguably the single deepest flaw in this president’s administration.

The president said he would surround himself with the “best people” to “make America great again.”

And during the 2016 Republican National Convention he stood at the lecturn and bellowed that “I, alone” can repair the things that ail this nation.

Fast-forward to this past week. The president accepted an invitation to meet with the North Korean dictator. Who did he inform of his decision? Was it his national security team? The vice president? The, um, secretary of state? None of the above.

He freelanced this one. Secretary of State Rex Tillerson, the nation’s top diplomat and the man who would need to know about such a momentous event before it is announced, was kept in the dark.

Donald Trump plans to meet with Kim no later than May. They’re supposed to talk about nuclear weapons and the North Koreans’ desire to become a bona fide nuclear power. The president is having none of it.

Where, though, is the pre-meeting preparation? How is this political novice — I refer to Trump — going to approach this event? Will he listen to a single word from the likes of Tillerson, or national security adviser H.R. McMaster? How about Vice President Mike Pence, who served in Congress before being elected Indiana governor?

My definition of “best people” no doubt differs from Trump’s use of the term. However, the president has assembled a team and has charged them with implementing policies that originate in the Oval Office.

It all begs the question, at least in my mind: Will the president let the “best people” do the things they must do or will be continue to act alone, pretending to be the world’s most indispensable human being?
