The North Atlantic Treaty was signed in 1949 with a solemn pledge: NATO members would not only defend one another against external aggression, they would safeguard “the freedom, common heritage and civilization of their peoples, founded on the principles of democracy, individual liberty and the rule of law.” These words matter. They mean that NATO is not simply a military alliance, it is a union of democracies. Its credibility rests on the idea that members govern themselves with the very liberties they claim to defend. Yet in recent years, several NATO states have drifted from these commitments, especially when confronted with the rise of conservative populist movements. Rather than respecting voters’ choices and engaging in open debate, many governments have chosen censorship, bans, and prosecutions. These tactics may preserve establishment power in the short run, but they corrode democracy and contradict NATO’s founding principles.
Consider France. Marine Le Pen’s National Rally and Éric Zemmour’s movement have electrified French politics since 2016. Their rise has been met not with the rough-and-tumble of democratic contestation but with judicial harassment. Le Pen was prosecuted for tweeting images of ISIS atrocities, stripped of her parliamentary immunity, and even ordered to undergo a psychiatric exam. Though she was ultimately acquitted, the process itself conveyed a chilling message: criticize Islamist terror too sharply, and you may find yourself in court. In March 2025, a French court convicted Le Pen of embezzling EU funds and imposed a five-year political ban, ensuring she could not stand in 2027 unless her appeal succeeded. The verdict provoked bipartisan unease, with even centrist leaders warning against judges deciding which candidates voters may support. Zemmour, too, has endured multiple hate-speech convictions for comments on immigration and Islam. Critics may despise his rhetoric, but the prosecution of a presidential candidate for campaign statements is a dangerous precedent in a democracy. France has also dissolved right-wing groups like Génération Identitaire and enacted censorship laws empowering courts to remove “fake news” during elections. These measures are defended as protecting democracy, yet they undercut the very pluralism and free expression on which democracy depends.
Germany’s case is no less troubling. The Alternative für Deutschland (AfD) has surged to become the country’s second party, at times topping national polls. In response, German authorities have unleashed censorship and surveillance. The 2018 NetzDG law forced platforms to delete “illegal” speech within 24 hours or face massive fines, leading to widespread over-censorship. AfD leaders have been investigated for tweets critical of Muslim immigration, their accounts suspended, and even criminal complaints filed for “incitement.” More serious still, Germany’s domestic intelligence agency placed the entire AfD under surveillance in 2021, treating the main opposition as a security threat. In 2025, the BfV escalated matters by officially designating AfD a “proven extremist organization,” enabling deeper spying and fueling calls for an outright ban. The government also banned Compact, a right-leaning magazine, raiding its offices and silencing its voice. Supporters of these actions argue that militant democracy requires restrictions to defend the constitutional order. Yet this logic threatens to collapse into authoritarianism, where the establishment alone decides who is fit to participate in politics. Even Friedrich Merz of the CDU warned that banning AfD would disenfranchise millions. NATO’s promise is not militant democracy, it is liberal democracy. A party with 20% of the electorate cannot be outlawed without abandoning the principle of free political choice.
The Netherlands offers further evidence of this pattern. Geert Wilders, leader of the Party for Freedom, has spent nearly a decade in courtrooms for his rhetoric. In 2016 he was convicted of inciting discrimination for asking supporters if they wanted “fewer Moroccans.” Judges later upheld the conviction in 2020, a remarkable fact: a politician was found guilty of a crime for repeating the desires of his own supporters. Thierry Baudet, leader of Forum for Democracy, has likewise faced judicial censorship, ordered to delete tweets comparing COVID restrictions to the Holocaust and barred from making such analogies in the future. In 2023, Baudet’s party was suspended from parliamentary debates for a week, silencing an elected faction. In 2024, Dutch prosecutors deemed FvD campaign ads to be criminal hate speech and summoned party leaders as suspects. These are not marginal figures, they are leaders of parties that regularly win millions of votes. When courts censor their campaign speech and parliaments suspend their voices, the line between democracy and repression grows perilously thin.
Romania provides perhaps the starkest case. In November 2024, nationalist candidate Călin Georgescu shocked elites by winning the first round of the presidential election. Days later, the Constitutional Court annulled the results, citing alleged Russian disinformation on TikTok. No direct evidence was provided. The annulment marked the first time in post-Cold War Europe that an election outcome was nullified. Georgescu was barred from running again, as was another nationalist contender, Diana Șoșoacă, who had earlier been excluded for making statements “contrary to democratic values.” Authorities also raided Georgescu’s associates, indicted him for “promoting fascist leaders,” and pushed through new speech laws against “extremist propaganda.” Tens of thousands of Romanians protested, chanting for free elections. Vice President J.D. Vance condemned the annulment as flimsy and undemocratic, while Elon Musk called it “a direct blow to the heart of democracy.” Whether one agrees with Georgescu’s politics or not, denying voters the ability to choose him betrays the essence of self-government.
Turkey, a NATO member since 1952, demonstrates how deep this erosion can go. After the failed coup of July 2016, President Erdoğan used emergency powers to close media outlets, jail journalists, and purge opposition parties. Conservative figures such as Meral Akşener of the İYİ Party have faced violent intimidation, including bullets fired into party headquarters. The pro-Kurdish HDP faces dissolution, with thousands of its members arrested. Erdoğan’s opponents are frequently prosecuted for “insulting the president.” Turkey has become a cautionary tale: once a flawed but functioning democracy, it now rules by fear and decree, in open defiance of NATO’s stated values.
What ties these cases together is a pattern. As populist conservatives gain strength, establishment parties respond with censorship, bans, and prosecutions. Leaders justify these measures as protecting democracy, yet the result is to deny voters the right to choose. This is not hypothetical. In France, Germany, the Netherlands, Romania, and Turkey, opposition leaders have been put on trial, stripped of office, or barred from elections. NATO’s charter does not permit such shortcuts. Article 2 commits members to “strengthen their free institutions” and “promote conditions of stability and well-being.” Free institutions require that voters decide which parties rise or fall, not courts, intelligence agencies, or ruling parties.
Some may object that NATO has no mechanism to police domestic governance. This is true. Yet the alliance’s legitimacy is based on the claim that it is an alliance of democracies. If its members behave like authoritarian regimes at home, that legitimacy collapses. How can NATO lecture others on free elections if its own members annul them? How can it condemn censorship in Russia or China when its leaders jail journalists or ban opposition parties? A double standard corrodes moral authority, and without moral authority, NATO risks becoming a hollow shell, a military pact without democratic meaning.
The US has begun to raise its voice. Secretary of State Marco Rubio criticized Germany’s surveillance of AfD as “tyranny in disguise.” Vice President Vance denounced Romania’s annulled election. Elon Musk warned that banning AfD would be an “extreme attack on democracy.” These interventions matter. They remind European allies that NATO’s credibility rests not only on tanks and treaties but on democracy itself. American taxpayers have poured billions into NATO. They have a right to insist that their allies honor the commitments that justify that expense. Defending free speech at home is as important as deterring threats abroad.
NATO’s founding treaty was right: democracy, liberty, and the rule of law are the alliance’s common heritage. But they are fragile. They cannot survive if members twist them into tools of repression. The populist right may be disruptive, it may be controversial, but it is a legitimate expression of voters’ will. To silence it with bans and prosecutions is to betray NATO’s promise. If NATO members wish to lead the free world, they must first practice freedom at home.
