Answer:
During World War I, the U.S. government implemented measures to address divisions among American immigrants. The Espionage Act of 1917 and the Sedition Act of 1918 were enacted to suppress dissent, leading to the arrest and deportation of some immigrants who were perceived as a threat to national security. Additionally, the Committee on Public Information worked to shape public opinion and promote a sense of unity, while the Americanization movement aimed to assimilate immigrants into American culture. Despite these efforts, divisions persisted, reflecting the challenges of managing diversity during a time of war.
