Why did America not fight fascism?

America did engage in fighting fascism during World War II, particularly against Axis powers like Nazi Germany and Fascist Italy. However, prior to entering the war in 1941, isolationist sentiments and a focus on domestic issues led to reluctance in intervening in European conflicts. Additionally, some Americans sympathized with fascist ideologies or were wary of entangling alliances, which delayed a more proactive stance against fascism until the attack on Pearl Harbor galvanized public opinion and political will.
