It seems safe to say that Donald J. Trump has reinforced something I have believed for the past 50 years or so, which is that we have redefined winning and losing wars.

I took part briefly in the Vietnam War, which is generally considered to be a conflict that the United States lost to a determined enemy. We won virtually every major engagement on the battlefield. We inflicted far more casualties on the enemy than they inflicted on us.

But we ended the war because we ran out of patience. We ran out of time. Vietnam was fighting to preserve its existence against a foreign power. I now accept the idea that we actually lost the Vietnam War. I am no less proud that I spent some time there doing my duty as ordered by my government.

Trump launched a war with Iran a few months ago. He decided to bomb the crap out of the place. Our aviators along with those from Israel sent bombs crashing into military facilities. Trump declared the war essentially to be over a few weeks after he started it. He kinda/sorta declared victory as well.

Then we entered talks to end the war. The sides emerged with a “memorandum of understanding” that they would stop the fighting. Iran wouldn’t obtain nuclear weapons, according to the MOU. Iran also would be able to sell its oil on the open market. The United States would lift the sanctions it imposed on Iran during the Barack Obama administration.

I have to ask: Is that winning?

Trump’s strategy looks more like that of a loser than a winner.

Now we’re back to bombing Iran. The Iranians have shut down the Strait of Hormuz — again! The price of oil is inching back up. We might lose more American lives; to date, 14 Americans service personnel have died.

To make matters even more maddening to American patriots … such as me: We don’t yet have a detailed explanation from the commander in chief as to our strategy for going to war, nor do we know of an exit strategy that Trump has cooked up in his feeble brain.
