This idea of a crisis within capitalism did have some plausibility. World War I, after all, had been a war among capitalists; it thereby provided the opportunity for the world’s first communist state to emerge. The Great Depression left the remaining capitalist states scrambling to save themselves rather than cooperating to rescue the global economy or to maintain the postwar settlement: Nazi Germany arose as a result. With the end of World War II, Stalin believed, the economic crisis was bound to return.
