'Warrior ethos' mistakes military might for true security and ignores the wisdom of Eisenhower

Hundreds of generals and admirals converged on Quantico, Virginia, on Sept. 30, 2025, after being summoned from across the globe by their boss, Pentagon chief Pete Hegseth, for a session that, as expected, covered what Hegseth often describes as the “warrior ethos.”

Listening quietly, they heard Hegseth promise to make the military “stronger, tougher, faster, fiercer and more powerful than it has ever been before,” and declare that he would fix “decades of decay” in the military.

President Donald Trump spoke for more than an hour in a political speech that derided presidents who came before him. He asserted that “political correctness” would be banished from the military.

The meeting came soon after Trump's Sept. 5 executive order renaming the Department of Defense the “Department of War.” With that change, Trump reverted the department to a name not used since the 1940s.

The change represents far more than rebranding — it signals an escalation in the administration’s embrace of a militaristic mindset that, as long ago as 1961, President Dwight D. Eisenhower warned against in his farewell address, and that the nation’s founders deliberately aimed to constrain.

The timing of this name change feels particularly notable when considered alongside recent reporting revealing secret U.S. military operations. In 2019, a detachment of U.S. Navy SEALs crept ashore in North Korea on a mission to plant a listening device during high-stakes nuclear talks. The risks were enormous: Discovery could have sparked a hostage crisis or even war with a nuclear-armed foe.

That such an operation was approved by Trump in his first term at all exemplifies an increasingly reckless militarism that has defined American foreign policy for decades. That militarism is the very subject of my book, “Dying by the Sword.”
