I continue to be a fan of White House chief of staff John Kelly.

He’s seeking to bring some discipline and order to the White House while trying to instruct the Oval Office occupant, Donald J. Trump, on how to act in a manner befitting his exalted title: president of the United States of America.

The former Marine four-star general, though, needs to develop a poker face when he’s forced to watch the president make an ass of himself on the world stage.

There he was at the United Nations this week, listening to the president talk about the “total destruction” of North Korea. Yes, Trump said that while speaking in the forum established in 1945 for the expressed purpose of finding peaceful solutions to international crises.

Gen. Kelly put his hand over his face. The question becomes: Was he mortified at what he was hearing? We don’t know, of course. He won’t say. The White House press operation said Kelly wasn’t reacting to anything in particular.

His reaction was somewhat similar to the body language he “spoke” while listening to the president refer to “both sides” being responsible for the Charlottesville, Va., riot that left a young counter protester dead after she was run over by a man with alleged ties to the white supremacists who provoked the riot in the first place.

Then again, we don’t know what Kelly was thinking at that time, either.

My point is that Kelly would do better for himself if he just sat there stoically without prompting observers all around the world to interpret body language messages.

Absent that kind of self-discipline, we are left to wonder out loud if he’s as disgusted at the boss as many of the rest of us.
