How did xenophobia impact American actions?

Xenophobia significantly influenced American actions throughout history, often leading to discriminatory policies and social tensions. During events like World War I and II, fear of foreign influence resulted in internment camps for Japanese Americans and the restriction of Immigration from certain countries. This prejudice also fueled anti-immigrant sentiments, manifesting in laws such as the Immigration Act of 1924, which aimed to limit newcomers from specific regions. Overall, xenophobia has shaped national policies and public attitudes, often at the expense of marginalized communities.
