 According to Gilman and Katz, antisemitism increased dramatically in the 1930s with demands being made to exclude American Jews from American social, political and economic life.During the 1930s and 1940s, right-wing demagogues linked the Depression of the 1930s, the New Deal, President Franklin Roosevelt, and the threat of war in Europe to the machinations of an imagined international Jewish conspiracy that was both communist and capitalist.A new ideology appeared which accused "the Jews" of dominating Franklin Roosevelt's administration, of causing the Great Depression, and of dragging the United States into World War II against a new Germany which deserved nothing but admiration.
