Final answer:
The United States had a delayed response to the treatment of Jews by the Nazi regime during the Holocaust due to various factors such as the prioritization of war efforts and anti-Semitism.
Step-by-step explanation:
The United States had a delayed response to the treatment of Jews by the Nazi regime during the Holocaust. One reason for this delay was that the rescue of Jews was not a priority for the US government during World War II. Another reason was the influence of anti-Semitism, isolationism, and xenophobia among some US citizens, which made it easier to discourage immigration. Additionally, the US State Department made it difficult for refugees to obtain entry visas into the United States, particularly during the 1930s.
