What was America's Response to the Holocaust before the War?
Americans paid attention and were outraged by the Nazi attacks through petitions where tens of thousands of Americans wrote, signed, and sent the documents to Washington. It tells that the American people had information on the persecution of the Jews in 1933. The Americans saw the early warning sign through Adolf Hitler, an authoritarian ruler who had spread an exclusionary and violent racist ideology that became the precursors to genocide. To protest, Americans showed up at rallies and boycotted German stores.
What could the US Have done differently?
Adolf Hitler paid close attention to the American media coverage and may have gone further, and faster, had he not read about the American people's disapproval. Fewer Jews may have gotten out of Germany, and America could have been less prepared to respond militarily. The rallies, petitions, and boycotts mattered a great deal with a network formed by like-minded Americans who in this period that later led some Americans to raise their voices even louder and take greater risks as Nazi persecutions of Jews worsened in Europe. There were warning signs on Hitler and Nazi Germany, weekly and the US would have acted. These signs included the targeting of Jews, communists, and other political opponents.
