Final answer:
The United States' indifference to the Holocaust can be categorized as situational irony, as it contradicted the country's reputation for humanitarian efforts.
Step-by-step explanation:
The United States' indifference to the plight of the Jews in the beginning stages of the Holocaust is ironic, and it can be categorized as situational irony. This is because the U.S. was known for its humanitarian efforts, yet it did not prioritize the rescue of Jews and made it difficult for refugees to obtain entry visas into the country. Despite President Roosevelt's public statements condemning persecution, the U.S. turned away Jewish refugees and refused to relax immigration quotas. The irony lies in the stark contrast between the U.S.'s reputation for humanitarianism and its lack of action during the Holocaust.
