If, on the other hand, you think that the contrasts with 1938 are more striking than the similarities, you see things differently. As a brief reminder of the contrasts: the Germany of 1938 was much richer and more powerful than the Iran of today. Germany was rapidly expansionist; Iran, despite its terrorist work through proxies, has not been. The Nazi leaders had engulfed the world in war less than a decade after taking power. Iran's leaders, oppressive and destructive, have not shown similar suicidal recklessness. European Jews of 1938 were stateless, unarmed, and vulnerable. Modern Israel is a powerful, nuclear-armed force. Moreover, the world after the first wartime use of nuclear weapons, of course by the United States, is different from the world before that point.
