Why did Adolf Hitler invade the Soviet Union despite the Molotov-Ribbentrop Pact?

Adolf Hitler’s invasion of the Soviet Union, known as Operation Barbarossa, was driven by his long-standing ideological goals rather than the German-Soviet Nonaggression Pact, which he viewed merely as a temporary measure of expediency.12

Hitler’s primary motivation was the pursuit of Lebensraum (living space), a core tenet of his ideology that necessitated the conquest of eastern territories to provide land, food, and resources for the German people. He held a deep-seated hatred for the Bolsheviks, whom he associated with a global Jewish conspiracy, and he viewed the Slavic populations as Untermenschen (subhumans) destined to be displaced or subjugated.13

While the 1939 pact allowed Hitler to avoid a two-front war while he secured dominance in western Europe, his suspicion of Joseph Stalin grew following Soviet territorial advances in the Baltic states, Bessarabia, and northern Bukovina. Concerned about the security of Romanian oil fields and convinced that the Red Army could be defeated quickly, Hitler accelerated his timetable to fulfill his ultimate vision of a continental empire.12
