What’s Trump’s parade really about? His bottomless insecurity.

Well, of course the president who claimed bone spurs to dodge the Vietnam War wants the biggest, bestest military parade ever, with lots of tanks and rockets and flags — zillions of flags — and fighter jets screaming overhead. Why is anyone surprised?

.. anyone who fails to cheer as the bands play and the troops march by will surely be guilty of treason.

.. Trump has already matched North Korean dictator Kim Jong Un in dangerous, unhinged rhetoric. Now it appears he hopes to surpass his rival in linear mileage of meaningless military display.

.. It is hard to imagine any other president summoning his generals to demand not a better strategy in Afghanistan, not a detailed plan for success in Syria, but rather an elaborate entertainment that gives him an opportunity to be seen reviewing the troops. In this reality-show presidency, it sounds like the kind of extravaganza that one could imagine as a series finale. If so, bring it on.

.. There is a semi-plausible argument that Trump could consciously use such a patriotic extravaganza as a wedge, the way he has used the national anthem protests in the NFL. It could be a with-me-or-against-me ploy. If you support the parade, you love America; if you don’t, you don’t.

.. But a celebratory military parade with nothing to celebrate could also highlight the gulf between Trump’s campaign promises and his actions. He pledged to wind wars down and bring the troops home; he has done quite the opposite.

.. My guess is that both his narcissism and his authoritarianism are at play in his need to honor himself with a parade.

.. Despite his boastful tweetstorms, the president clearly realizes that his approval ratings are historically low. He is so unpopular that he will not even risk a state visit to London to open the new U.S. Embassy there for fear of being humiliated by mass protests.

.. The campaign-style rallies he so enjoys do not appear well-designed to advance a political agenda; they do, however, boost his spirits and massage his ego.

.. He would be saluted and serenaded to his heart’s content. It would be an egomaniac’s heaven.

.. Trump’s big parade would also be a massive display of power — not so much the nation’s as his own. There is not a soul on Earth who doubts the overwhelming strength of the U.S. military. I can think of one soul, however, who is insecure enough in his own authority that he accuses members of Congress who do not stand and applaud him of treason.

Let’s Make a Wall Deal

The House passed a bill that would pony up nearly $1.6 billion for the first stretch of Donald Trump’s pet project.

.. And the release of a government report that estimates the Department of Homeland Security would have to screen 750,000 applicants to meet the president’s target for new Border Patrol hires.

.. And the discovery that Trump’s sudden announcement about barring transgender volunteers from the military was actually all about getting money to start building the … barrier.

.. But final passage was being held up by social conservatives, who were trying unsuccessfully to add an amendment barring the military from paying for gender reassignment surgery.

.. The vision of what the president wants in a wall keeps shifting. At first it was a 2,000-mile, 50-foot-tall concrete monolith. Then it became maybe a little shorter, and something with solar panels.

.. Trump also wants to hire 5,000 new Border Patrol officers, which the Department of Homeland Security’s inspector general estimates would require the screening of 750,000 applicants. The jobs, it seems, can be both demanding and extremely boring. Clearly, the only answer would be to bring in foreign workers. As our president said when he was explaining why Mar-a-Lago keeps getting special visas to hire cooks and cleaners from abroad, “It’s very, very hard to get people.”

.. It’s not clear he thinks building it would do any good, but he certainly believes it makes him look good.

.. But Trump was fixated on his promise to make Mexico pay for the wall — not actually making it happen so much as making Mexico say it would happen. Or that “we will work it out.” Or just not mentioning that Mexico was never going to put up a dime. (“… you cannot say that to the press. The press is going to go with that and I cannot live with that.”)

.. So it’s all about image.

.. The chances we’ll ever see this $20-billion-plus project completed are minimal. But just keeping up pretenses will mean an enormous waste of money and effort. Maybe we could make a deal like the one Trump was trying to urge on the Mexicans. Whenever the subject of the wall comes up, we would all agree to say, “Hey, you never can tell.”
