The history of Donald Trump’s pre-business history is well-known.

He sought to avoid service in the military during the height of the Vietnam War. He received dubious medical deferments citing bone spurs or some such ailment that kept him out of being eligible for military service.

He went into business. Made a lot of money. Lost a lot of money. Had mixed success as a business mogul. Then he went into politics. He ran for president of the United States. He won!

So for this current president to dress down men who have served their country honorably, in combat, thrust themselves into harm’s way is insulting, degrading and astonishingly unpatriotic.

Two reporters for the Washington Post, Philip Rucker and Carol Leonnig, have written a book that tells just how disgraceful Trump’s conduct has gotten with regard to the military high command. An excerpt from that book tells of a meeting in a Pentagon room called The Tank. The brass sought to explain the nuts and bolts of military matters to the commander in chief. He was having none of it.

He called the generals “babies and dopes.” He has told them they are “losers” and said he wouldn’t “go into battle” with them.

I am trying imagine, were I one of those decorated combat veterans, hearing such denigration coming from the commander in chief. The entire world knows this man’s history. We all know that, when he had the opportunity to serve his country, he chose another path.

Don’t misunderstand me on this score. I do not begrudge a president who’s never worn the nation’s military uniform. Two recent presidents did not serve: Barack Obama or Bill Clinton. Neither did Franklin Roosevelt or Woodrow Wilson, both of whom led this country through two world wars.

What is so objectionable is the snarky attitude this president demonstrates to individuals who have done what he sought to avoid doing. That he would speak to these patriots in such a manner is disgraceful on its face.
