World War II pushed the world's nations to defining moments of realization.In the United States the century long cultural beliefs regarding gender and racial equality were turned on their head. America simply did not have time to tolerate discrimination in the work force or on the battlefield. Every man and woman regardless of race or ethnicity was needed to help pull the Allies to victory. Millions of mothers, daughters and wives entered the industrial work force in unprecedented numbers for the first time. African, Japanese, Latino and Native Americans among others entered into military service and almost exclusively proved their valor beyond even the highest expectations. President Franklin D. Roosevelt stated "Americanism is not and has never been a matter of race or color. Americanism is a matter of mind and heart." His successor President Harry Truman would in turn desegregate the U.S. Armed Forces in 1948.
