George Washington supported an isolationist policy so Americans would avoid "entangling" alliances.
Step-by-step explanation:
The early leaders of the United States including George Washington believed that the nation would become vulnerable to foreign influence over important issues concerning the country if the federal government allows citizens to form alliances with foreign individuals or business entities.
To avoid that from happening, George Washington convinced his subordinates at various levels to comply with his idea of isolationism and work accordingly. Thomas Jefferson, another influential leader who led America after George Washington, chose to follow the same policy during his regime as the president.
