American efforts to protect the nation's identity after World War I was a result of

growing concerns about the threat of foreign influence and the desire to preserve American values and traditions. The country had just emerged from a devastating war with significant changes to society, including increased immigration, cultural shifts, and a more connected global community. This led to fears that American identity was at risk of being diluted or eroded. As a result, the government and various organizations implemented measures to promote national unity, patriotism, and a sense of American identity. This included actions such as promoting Americanization programs for immigrants, enforcing stricter immigration policies, and promoting symbols of American nationalism, such as the flag and the Pledge of Allegiance. Additionally, efforts were made to strengthen national security and protect against perceived threats to American values and traditions. Overall, these efforts were aimed at safeguarding and preserving the nation's identity in the aftermath of World War I.
