Between the fall of Poland and the German invasion of France, western Europe spent months in an uneasy lull, with Britain and France technically at war with Germany but neither side attacking. This History Hit film traces how that stretch of inaction, later nicknamed the Phony War, let leaders and civilians alike convince themselves the worst might be avoided. It backs up further to show how the crisis built: Japan's invasion of China, Mussolini's fascist takeover in Italy, and Hitler's dismantling of German democracy, each expanding unchecked while other powers hesitated to respond. Archival footage and expert narration lay out the diplomatic failures and military unpreparedness that let aggression go unanswered again and again, from the Rhineland to Austria to Czechoslovakia. The film's argument is that the false calm of late 1939 was not an accident but the product of years of appeasement and wishful thinking, a habit of mind that made the sudden German assault on France and the Low Countries in 1940 so shattering when it finally came.
