Donald Trump continues to exhibit an astonishing lack of self-awareness. Indeed, the irony of his sudden bolting from an international meeting with military allies reveals that point.

There he was at the North Atlantic Treaty Organization meeting in London. He trashed French President Emmanuel Macron, called Canadian Prime Minister Justin Trudeau “two-faced” and then became the subject of a hot-mic exchange among NATO leaders who were poking fun at the president.

He left the NATO conference and jetted back to the United States.

What is astonishing in the extreme is that Trump seemed to get mad at the leaders’ laughing at his expense. He has no awareness of the kind of treatment he has leveled on his political foes and, indeed, even at his allies.

He has tossed out insults and epithets at will. He hangs goofy nicknames on those with whom he disagrees. He dishes out innuendo as rapidly as a blackjack dealer.

So he gets chided by his colleagues at a NATO meeting and then flies out of there? What gives with this guy?

He vowed while campaigning for the presidency to get rid of the laughingstock label he said was being hung on the United States. Well, maybe he has done that … by giving other world leaders reason to laugh at him.
