Trump calls for Department of War to strengthen US deterrence

At first, I was skeptical. “Defense” suggests restraint, a principle I consider vital to U.S. foreign policy. “War” suggests aggression. But for the first 158 years of the republic, that was the honest name: the Department of War.

A Department of War recognizes the truth: The military exists to fight and, if necessary, to win decisively.

The founders never intended a permanent standing army. When conflict came — the Revolution, the War of 1812, the trenches of France, the beaches of Normandy — the nation called men to arms, fought, and then sent them home. Each campaign was temporary, targeted, and necessary.

From ‘war’ to ‘military-industrial complex’

Everything changed in 1947. President Harry Truman — facing the new reality of nuclear weapons, global tension, and two world wars within 20 years — established a full-time military and rebranded the Department of War as the Department of Defense. Americans resisted; we had never wanted a permanent army. But Truman convinced the country it was necessary.

Was the name change an early form of political correctness? A way to soften America’s image as a global aggressor? Or was it simply practical? Regardless, the move created a permanent, professional military. But it also set the stage for something Truman’s successor, President Dwight “Ike” Eisenhower famously warned about: the military-industrial complex.

Ike, the five-star general who commanded Allied forces in World War II and stormed Normandy, delivered a harrowing warning during his farewell address: The military-industrial complex would grow powerful. Left unchecked, it could influence policy and push the nation toward unnecessary wars.

And that’s exactly what happened. The Department of Defense, with its full-time and permanent army, began spending like there was no tomorrow. Weapons were developed, deployed, and sometimes used simply to justify their existence.

Peace through strength

When Donald Trump said this week, “I don’t want to be defense only. We want defense, but we want offense too,” some people freaked out. They called him a warmonger. He isn’t. Trump is channeling a principle older than him: peace through strength. Ronald Reagan preached it; Trump is taking it a step further.

Just this week, Trump also suggested limiting nuclear missiles — hardly the considerations of a warmonger — echoing Reagan, who wanted to remove missiles from silos while keeping them deployable on planes.

The seemingly contradictory move of Trump calling for a Department of War sends a clear message: He wants Americans to recognize that our military exists not just for defense, but to project power when necessary.

Trump has pointed to something critically important: The best way to prevent war is to have a leader who knows exactly who he is and what he will do. Trump signals strength, deterrence, and resolve. You want to negotiate? Great. You don’t? Then we’ll finish the fight decisively.

That’s why the world listens to us. That’s why nations come to the table — not because Trump is reckless, but because he means what he says and says what he means. Peace under weakness invites aggression. Peace under strength commands respect.

Trump is the most anti-war president we’ve had since Jimmy Carter. But unlike Carter, Trump isn’t weak. Carter’s indecision emboldened enemies and made the world less safe. Trump’s strength makes the country stronger. He believes in peace as much as any president. But he knows peace requires readiness for war.

Names matter

When we think of “defense,” we imagine cybersecurity, spy programs, and missile shields. But when we think of “war,” we recall its harsh reality: death, destruction, and national survival. Trump is reminding us what the Department of Defense is really for: war. Not nation-building, not diplomacy disguised as military action, not endless training missions. War — full stop.

Names matter. Words matter. They shape identity and character. A Department of Defense implies passivity, a posture of reaction. A Department of War recognizes the truth: The military exists to fight and, if necessary, to win decisively.

So yes, I’ve changed my mind. I’m for the rebranding to the Department of War. It shows strength to the world. It reminds Americans, internally and externally, of the reality we face. The Department of Defense can no longer be a euphemism. Our military exists for war — not without deterrence, but not without strength either. And we need to stop deluding ourselves.
