Final answer:
George Washington advocated for a U.S. foreign policy based on neutrality, justice, and peace, avoiding entangling alliances, especially with Europe, to promote national unity and economic growth.
Step-by-step explanation:
Following George Washington's Farewell Address, he advocated for a United States foreign policy that emphasized impartiality and avoidance of permanent alliances. His address expressed the sentiment that the young nation should "observe good faith and justice toward all nations; cultivate peace and harmony with all" and steer clear of entangling political alliances, especially with Europe which had different interests and was often involved in conflicts not directly related to the U.S. Washington valued national security and economic development, which he believed were reliant on the peaceful settlement of Western lands and navigation rights. By focusing on internal strength and unity, he hoped the U.S. would be respected on the international stage without being drawn into foreign wars or disputes.
