That astonishing sideshow that commenced today in the Cabinet Room of the White House left me fairly speechless.

Why? Because there is too much on which to comment. Donald Trump’s non-stop riff covering the government shutdown, The Wall, the military, James Mattis’ resignation/firing, and God knows what else has left many of us out here grasping for something on which to analyze.

I’ll go with two items that jumped out at me.

Trump said, “I think I would have been a good general, but who knows?” Well, Mr. President, you had your chance back in the 1960s. While many of us were answering the call to duty during the Vietnam War, young Donald Trump received (cough, cough!) medical deferments associated with, um, bone spurs.

I had flat feet in 1968, which I always thought was a disqualifier. The U.S. Army induction center in Portland, Ore., didn’t accept that idea. So . . .  off I went.

The future president got five deferments. The New York Times recently revealed that the circumstances of those deferments were at best questionable, that the doctor who “diagnosed” the bone spurs allegedly did so as a favor to young Donald’s father, Fred. Thus, I won’t buy into his goofy notion about how good a general he would have been.

Then he said this about James Mattis, the now-former secretary of defense. “What did I get out of” his service? “Not much,” Trump said.

OK. Let’s see. The oath that Mattis took was to protect the country, to serve the country, to defend the Constitution. He did not swear an oath to serve the president. He did not declare his adherence to the individual who nominated him to run the Pentagon.

Then the president said he “essentially” fired the defense secretary.

Right there is yet another demonstration from Donald Trump that this individual does not understand the true meaning of public service. He has shown one more time how patently unfit he is to serve as commander in chief of the finest military apparatus the world has ever seen.
