A new account emerged in the wake of the Vietnam War. U.S. involvement in Vietnam disillusioned some historians and created antipathy towards the American position. In the 1960s and 1970s, the revisionists stressed that American expansionism was the cause of the Cold War. They pointed out that, at the end of the Second World War, the Soviet Union was severely weakened, whereas the United States prospered and possessed a monopoly on the atomic bomb. According to the revisionists, Stalin’s main priority was to recover from the devastating war years. They placed the cause of the Cold War in the nature of capitalism and viewed Marshall Aid as a way of seeking new markets and expanding the U.S. economy. The Soviet Union thus correctly understood that their sphere of influence in Eastern Europe was in danger.
