The economic troubles of the 1930s were worldwide in scope and effect. Economic instability led to political instability in many parts of the world. Political chaos, in turn, gave rise to dictatorial regimes such as Adolf Hitler's in Germany and the military's in Japan. (Totalitarian regimes in the Soviet Union and Italy predated the depression.) These regimes pushed the world ever-closer to war in the 1930s. When world war finally broke out in both Europe and Asia, the United States tried to avoid being drawn into the conflict. But so powerful and influential a nation as the United States could scarcely avoid involvement for long.
