Evolving Alliances: U.S. Foreign Policy from Isolationism to Engagement

This chapter explores the historical reluctance of the U.S. to form formal alliances throughout the 19th century and the consequences of this stance leading into World War I. It evaluates the transition of American foreign policy from Washington's initial avoidance of alliances to the establishment of the United Nations as a response to new global threats during and after World War II. The narrative highlights debates over military pacts like NATO and the evolution of U.S. strategic thinking regarding international cooperation and security.
