Answer: Consideration of American responses to Nazism during the 1930s and 1940s raises questions about the responsibility to intervene in response to persecution or genocide in another country. As soon as Hitler assumed power in 1933, Americans had access to information about Nazi Germany’s persecution of Jews and other groups.

Even after the US entered World War II, the government did not make the rescue of Jews a major war aim. (I think this is it i dont know im pretty sure)
