Which principle did Roosevelt promote regarding dictators during WWII?

Roosevelt's stance during World War II included the belief that dictatorships posed a significant threat to global peace and democracy. He was a proponent of the idea that the rise of such regimes should be actively countered to prevent their resurgence after the war. This reflects his commitment to promoting democratic ideals and ensuring that tyrannical governments that had caused vast suffering and conflict would not regain power. The focus on preventing dictators from coming to power again aligns with his vision of fostering a world order based on democratic principles and collective security, as demonstrated by his support for the establishment of the United Nations after the war as a means to promote peace and prevent future conflicts driven by authoritarian rule.
