The idea that dissent should be locked up is alarming, but not unprecedented. This call has recently been made by Yair Kleinbaum:

Throughout history, moments of national fear and crisis have too often produced a reflexive response: the suppression of voices that question, challenge, or complicate the dominant narrative. This is particularly evident in wartime, when paranoia and urgency combine to justify measures that would otherwise seem unconscionable. The suggestion that people who disagree with prevailing policy or opinion should face incarceration is not merely a theoretical concern — it is a direct echo of past episodes in which fear, suspicion, and nationalism overrode civil liberties.
During World War II, for instance, the United States and Australia both interned citizens of German, Italian, and Japanese descent. In America, Japanese Americans — many of them U.S. citizens — were forcibly removed from their homes and placed in internment camps. Australia, too, implemented internment policies against those deemed "enemy aliens," including German and Japanese residents. These actions were justified at the time as necessary for national security, yet in retrospect, they were driven as much by paranoia, racism, and public hysteria as by any concrete threat. Entire communities were punished not for acts of aggression, but for their ancestry or associations, illustrating the peril of conflating dissent — or simply difference — with disloyalty.
The logic that dissent itself constitutes danger is deeply troubling. War and crisis do not automatically confer the right to silence or punish critical voices. In fact, open debate and scrutiny are essential precisely because they prevent overreach, abuse, and error. When governments begin to equate disagreement with subversion, the line between legitimate national defence and authoritarian repression blurs. History shows that such measures rarely stop at temporary wartime necessity; they leave lasting scars on civil society, foster mistrust, and undermine the very principles they claim to protect.
The current rhetoric echoing these past missteps is a reminder that the allure of authoritarian solutions during crisis is persistent. Calls to "lock up" dissenters, to criminalise disagreement, or to treat minority communities with blanket suspicion are not anomalies — they are part of a recurring pattern in human societies under stress. The parallels to World War II internment are stark, but the principle extends beyond that period: any society that allows fear to override the rule of law, due process, and freedom of expression risks repeating history's mistakes.
This is not merely a theoretical warning; the consequences are tangible. Targeting dissenters generates fear, stifles debate, and erodes trust in institutions. It produces self-censorship, chills scientific and political inquiry, and transforms the public sphere into a space where only conformity is safe. Such measures may be presented as temporary or necessary, but history demonstrates they often persist long after the original threat has passed, corroding democratic norms and undermining the social fabric.
Ultimately, the lesson is clear: dissent is not the enemy, even in times of crisis. Protecting the right to question, critique, and challenge authority is fundamental to preventing overreach and preserving liberty. Paranoia and fear may tempt societies toward harsh measures, but the consequences — internment, censorship, and persecution — serve as cautionary tales. In the balance between security and freedom, history teaches that suppressing dissent rarely makes a society safer, and almost always makes it less just.
