Who replaced the hun as the object of american fear and hatred?

After World War I and the decline of the "Hun" stereotype associated with German soldiers, the object of American fear and hatred shifted primarily to communists, particularly during the Red Scare of the 1920s and again in the Cold War era. The rise of the Soviet Union and the spread of communism fueled fears of subversion and espionage within the United States. Additionally, groups such as Nazis during World War II and later, in the post-9/11 era, Islamic extremists also became focal points of American anxiety and hostility.
