How did ww1 affect public opinion in the US?

World War I significantly shifted public opinion in the U.S. towards a more interventionist stance in foreign affairs. Initially, many Americans favored neutrality, but as the war progressed, factors like German U-boat attacks and Propaganda highlighting atrocities in Europe swayed public sentiment in favor of joining the conflict. The war also fostered a sense of national identity and unity, as well as a growing belief in the U.S. as a global leader advocating for democracy and peace. However, it also led to increased scrutiny and suspicion of dissent, particularly towards immigrants and anti-war activists.
