In the early 1930s and early 1940s, the US response to the Holocaust was marked by a lack of awareness and a focus on domestic issues exacerbated by the Great Depression, with strict immigration policies severely limiting the number of refugees allowed into the U.S. As the U.S. entered World War II in 1941, reports of mass atrocities against Jews in Europe began to surface, but the priority remained winning the war, and significant resources for rescue operations were not diverted. The establishment of the War Refugee Board (WRB) in 1944 marked a turning point, providing a more organized response to the Holocaust. After the war, the liberation of concentration camps and the Nuremberg Trials brought a clearer understanding of Nazi atrocities and the need for justice. The Displaced Persons Act of 1948 allowed entry for some survivors. The post-war period saw increased awareness, memorialization, and efforts to bring Nazi war criminals to justice, with the establishment of the U.S. Holocaust Memorial Museum in 1979 and the inclusion of Holocaust education in curricula. A complex historical process, the U.S. response to the Holocaust reflected evolving priorities, information flow, and policy changes over time.
