In September 2016 I went to a televised forum with the two leading presidential candidates and asked Donald Trump about military policy in Iraqmegapanalo, where I served with the Marine Corps several years earlier. He told me America should “take the oil.” Then he said it again: “Take the oil.”

A dumb answer, but a clear one. If we’re going to put American lives at risk, let’s get something out of it. Something concrete, something valuable. You can’t touch an ideal, but you can shove your grasping hands deep into a black pool of liquid gold. A few years later, explaining our military presence in Syria, Mr. Trump said he was keeping troops there “only for the oil.” What a thing to ask soldiers to fight for.

When it comes to articulating a vision of American warfare, Mr. Trump is the least hypocritical president of my adult life. He does not promise to spread democracy or human rights or a liberal, international rules-based order. He does not claim we’re a shining city on a hill. “We’ve got a lot of killers,” he has said instead. “What? You think our country’s so innocent?” He has stated smaller, less idealistic goals: our borders, secure; our economy, soaring; our wars, ended. These are most presidents’ goals, of course, but Mr. Trump expresses them plainly, even crassly.

Given this, it seems unlikely that Mr. Trump will start a disastrous war in a faraway country to “free its people and defend the world,” as George W. Bush did, or make appeals to international law in Ukraine while ignoring it in Gaza, like President Biden. And if and when Mr. Trump does kill people overseas, he’s more likely to claim they “died like a dog” than perform hand-wringing the way Barack Obama did about how he wanted to save them but “the world they were a part of, and the machinery I commanded, more often had me killing them instead.” After so much presidential windbaggery, Mr. Trump’s bracing cynicism is almost refreshing.

But this sort of amoral pragmatism, especially in matters of war, has its limits and dangers. It will inevitably run up against a core belief in America’s identity as a nation, the belief in the moral obligation to strive to conduct and fight wars honorably. It’s a belief I still hold and that millions of Americans do, too.

When I started Marine training, our instructors constantly harangued us candidates about the core military virtues and told story after story of past heroes who had lived them. For men and women to trust their lives to one another in combat, you need a shared set of values and commitments, which is why all great militaries teach their recruits something closer to religious devotion than business calculation.

No one was injured in the escape, which happened about 12:30 p.m. on Sunday. Firefighters for the city of North Attleboro who were working at a rodeo at the Emerald Square Mall said they had seen eight bulls break loose from their pen, the fire chief said in a previous statement.

Maj. Gen. Patrick S. Ryder, the Pentagon press secretary, declined to say exactly how many troops were deploying, citing operational security.
