Jacob Rees-Mogg, the former Conservative minister who lost his parliamentary seat in 2024, invited Tucker Carlson into his home to record a podcast episode. What he got was a live demonstration of how right-populist isolationism has metastasized from skepticism about Ukraine into outright WWII revisionism. Carlson questioned why Britain entered the Second World War, suggested Germany had a legitimate claim over parts of Poland, and responded to Rees-Mogg's warning about a Nazi invasion with: "Who cares? There are a lot of people in Britain who can't speak English. So it would be nice to have at least a European language spoken in your country." Rees-Mogg, not typically cast as a voice of liberal internationalism, found himself playing straight man to an increasingly unhinged thesis. He told Carlson he was "verging on defending Hitler" and added: "I think this is not really what you want to be doing." Carlson deflected with sarcasm — "I guess I'm just a secret Nazi" — before insisting he was not. The exchange is remarkable less for its shock value than for the structural position it reveals: a mainstream American media figure with tens of millions of followers is now willing to float Nazi apologetics on camera, and the person pushing back is a traditionalist Tory who would normally be the rightmost voice in any British political conversation. Carlson's trajectory matters here. After leaving Fox News and losing faith with Donald Trump — largely over Trump's willingness to engage in foreign conflicts — Carlson built an independent media platform that has steadily escalated its contrarianism. He interviewed Vladimir Putin. He has taken a sympathetic position toward Russia on Ukraine. The WWII gambit is the logical terminus of that arc: if American intervention abroad is always wrong, then the Allied cause itself becomes negotiable. The reaction from within Carlson's own political ecosystem was swift and instructive. Mike Huckabee, the Republican serving as US ambassador to Israel, posted: "When it seemed impossible for Toxic Tucker to descend deeper into the sewer here he goes opining that UK should have let Nazis take over. Forget that Hitler murdered 11 million people?" That a Trump-appointed ambassador is publicly calling Carlson's comments sewage signals real factional stress on the American right, not just performative outrage. The episode exposes a structural problem in the transatlantic right-populist alliance. British conservatives like Rees-Mogg share some instincts with American MAGA populism — Brexit nationalism, anti-woke sentiment, fiscal conservatism. But the Second World War is the foundational myth of modern Britain in a way it simply is not for American isolationists. When Carlson dismisses the war, he is not just being provocative — he is making himself functionally unusable as an ally for any British conservative who wants to remain credible. The broader extraction is informational. Carlson's platform monetizes escalating provocation. Each controversy drives engagement, subscriptions, and cultural relevance. The cost is borne by the quality of public discourse about history, alliances, and the actual stakes of geopolitical decisions. Rees-Mogg, seeking a post-politics media career, walked into a content trap — lending his credibility as a former minister to a conversation that ended with him having to explain why fighting Hitler was a good idea. What this exchange reveals, stripped of the spectacle, is the point at which isolationist contrarianism stops being a foreign policy position and becomes historical illiteracy with an audience. The question is not whether Carlson believes what he said — it is whether the incentive structure of his platform makes it rational to say it regardless.
