I was burdened all day by the two speeches given to the assembled military at Quantico this morning. I did what I always do, I retreated into history to help me understand.
History has shown us time and again that the scariest threat isn’t always portrayed as coming from beyond our borders. Often, leaders find it far more effective to warn of an “enemy within.” It’s a phrase that turns neighbors into traitors, critics into subversives, and difference into danger. Once planted, it grows into fear and, eventually, justification for repression.
Hitler and the Nazi Machine
In 1930s Germany, Adolf Hitler didn’t simply blame external enemies for the nation’s troubles—he painted Jews, Romani people, people with disabilities, and political dissidents as the rot inside the German body. They weren’t just different; they were poison, a hidden cancer.
By labeling these groups as “enemies within,” Hitler made persecution seem like self-defense. That rhetoric set the stage for the Holocaust, one of the most systematic and horrifying genocides in human history. The key lesson: words prepared the ground long before weapons did.
McCarthy’s America
Fast forward two decades and cross the Atlantic. In the 1950s, Senator Joseph McCarthy unleashed his infamous hunt for communists. The Soviet Union was a real external threat, yes—but McCarthy’s genius (and cruelty) was in convincing Americans that the real danger was sitting next to them at work, or even in their own family.
Actors, teachers, journalists, government employees—anyone could be accused of being an “enemy within.” Careers were ruined, reputations destroyed, and free speech suffocated. The irony? McCarthy never actually uncovered the vast conspiracy he claimed existed. But the damage was already done.
Why It Matters Today
We’d love to think we’ve learned. But look around: the phrase hasn’t gone away—it’s just rebranded. Whether it’s immigrants, political opponents, journalists, or religious minorities, painting them as a hidden enemy remains a powerful tactic.
And it works because it flips the script. Instead of debating ideas, it stirs paranoia. Instead of solving problems, it hunts scapegoats. Instead of democracy, it builds division.
When leaders call critics or minorities the “enemy,” they aren’t just pointing fingers—they’re setting fire to the foundations of trust, tolerance, and truth. And history shows us exactly where that road can lead.
The Takeaway
The “enemy within” isn’t about safety—it’s about control. Hitler used it to justify genocide. McCarthy used it to build power. Today, it’s still used to divide and silence.
The question isn’t whether we’ll hear the phrase again. We will.
The real question is: will we recognize it for what it is before the damage is done?
