Background Statement
Though a number of factors contributed to the United States’ ineffective response to the Jewish or, as it was often softened, “European” refugee crisis of the 1930s, a small number of those factors stand out as major contributors to America’s failure to rescue more Jews from Nazi genocide. The situation almost a hundred years ago is similar to today’s stance on immigration and refugees. Vocal anti-refugee/anti-immigrant sentiments are again widely reported in the news media and the American public continues to voice its opposition to immigration in general, regardless of country of origin, as demonstrated in opinion polls throughout the 20th century [see Pew Research Center overview]. This consistent public lack of support for immigrants and refugees has been exasperated by poor government policy. This confluence of public opposition or at least indifference and restrictive government policy had the most dire of effects in the decade leading up to the Holocaust.
