The claim that "the entire political class was wrong about Hitler" is a broad generalization that is partly supported but materially overstated. **What is accurate:** The dominant establishment view in 1930s Britain was appeasement, which proved wrong. The Munich Agreement vote in October 1938 passed 366–144, with no Conservative voting against and Churchill's small group only abstaining. MPs who warned about Hitler were indeed attacked as "warmongers," threatened with deselection, had their phones tapped, and were disparaged by Chamberlain (who dubbed a group of young anti-appeasement Conservative MPs the "Glamour Boys"). Churchill was a marginal, isolated figure for much of the decade, and his warnings about German rearmament were largely dismissed. The appeasement consensus was strong across both front benches. **What is overstated:** The word "entire" and Farage's figure of "20" MPs who raised the alarm significantly understate the opposition. The Labour Party (154 seats after 1935) generally opposed appeasement and voted against Munich (144 votes against). Beyond Churchill, there were Anthony Eden, the "Glamour Boys" (Ronald Cartland, Robert Bernays, Harold Nicolson, Ronald Tree, etc.), Josiah Wedgwood, and various "diehard" Conservative MPs who pressed for faster rearmament. While anti-appeasement voices were a minority and were marginalized, they numbered well above 20 and included figures from multiple parties. The claim that "the entire political class" was wrong erases this substantial dissenting minority.
