What were the arguments against US entry in World War 1?

Arguments against U.S. entry into World War I included concerns about the costs of war, both in terms of American lives and financial resources. Many Americans felt a strong isolationist sentiment, believing the conflict was a European issue that did not directly threaten U.S. national security. Additionally, there were fears about entangling alliances and the potential loss of civil liberties, as some believed wartime measures could infringe on individual rights. Lastly, the strong anti-war sentiment among various groups, including pacifists and socialists, further fueled opposition to involvement in the conflict.
