Why did the war leave US government stronger than before?

The war left the U.S. government stronger than before due to the expansion of federal powers and responsibilities necessitated by wartime efforts, such as economic mobilization and military organization. The need for effective coordination led to the establishment of new agencies and a more centralized authority, enhancing the government's role in citizens' lives. Additionally, wartime experiences fostered a sense of national unity and purpose, reinforcing the legitimacy and authority of the federal government in the eyes of the public.
