The man who loves to tweet, Donald Trump, has a president problem.

On his Inauguration Day, CNN’s Jim Acosta snapped the image of the glorious sunrise and tweeted it. Since then, there has been nothing but shade to, or from, President Trump and the media.

Mr. Trump does what he enjoys and he masters what he does, or so he tells us. On occasion, he can use charm, even making up words that stick, such as “bigly.” What he avoids is being serious about serious matters. He cannot put down his phone and work.

Since January 20, I have been hoping that something, or someone, would help him in his new job. Instead, he plays.

Social media is his best game. He loves its destructive power. The sad truth is that social media works best when the content is angry.

If you intend to create breaking news, interrupting something important to turn and cast the light upon yourself, you have to use a social media platform that is built to deliver your message, instantaneously, around the globe. Tap. Click. Boom.

Three terrorists used a truck and knives to kill and maim on London Bridge one night. Eight minutes later they were shot dead by the police.

Our president, no doubt watching on television, likely by himself, picked up his phone and tweeted an insult to the Mayor of London.

In the business of social media and in the mind of our 45th president, that was a bigly win. The world’s hearts all stopped in horror to focus on one bridge in London, yet Donald Trump smashed through with all the indignity of a frat boy photobombing the funeral of a child.

“Embarrassing?” We are five time zones past embarrassing.

Donald Trump’s behavior over the last three weeks has me thinking that he fears his job, that he is protesting the seriousness of it. He fears the other leaders of the world. He resents his staff telling him how to act or what to say. During the campaign, he bellowed “NATO is obsolete” as if saying so were an act of derring-do.

On May 25, Donald Trump was scheduled to address the North Atlantic Treaty Organization.

His national security team, nicknamed MMT (McMaster, Mattis, Tillerson), prepared the president’s remarks in order to “explicitly reaffirm America’s commitment to mutual defense of the alliance’s members, a one-for-all, all-for-one provision that looks increasingly urgent as Eastern European members worry about the threat from a resurgent Russia on their borders.”

Donald did not speak the only words for which his speech, and that occasion, existed. My guess is that there are no limits to his juvenile defiance.

Think about that. An American president, whose predecessors include FDR, Truman, and Eisenhower, fails NATO.

Today is the 73rd anniversary of D-Day and Operation Overlord. Launched at enormous risk, in bad weather, after enormous preparation, assisted by Operation Double Cross (the successful subversion of every German spy in England) led, ultimately, to the defeat of Nazi Germany and the liberation of Europe.

The night before the launch, Dwight Eisenhower closed his short note “In Case of Failure” with this sentence:

If any blame or fault attaches to the attempt it is mine alone.

Which man defines America?
