Analyze how U.S. foreign policy developed. Trace evolution of American approach to international relations from founding through present. **Why This Matters:** Understanding how U.S. foreign policy has evolved helps students see how historical experiences shape current approaches to global affairs and evaluate whether current policies are appropriate. **Examples:** - **Early Isolationism:** Students study George Washington's Farewell Address warning against "entangling alliances" and how the U.S. avoided European conflicts for much of its early history. They analyze the Monroe Doctrine and how it asserted U.S. influence in the Americas while avoiding European affairs. - **Rise to Global Power:** Students examine how the Spanish-American War and World War I marked the U.S. emergence as a world power. They study how the U.S. initially rejected the League of Nations but later embraced international leadership. - **Cold War Era:** Students analyze how containment policy shaped U.S. actions from the Truman Doctrine through the fall of the Soviet Union. They examine how the U.S. intervened in conflicts (Korea, Vietnam) and supported allies to prevent communist expansion. - **Post-Cold War:** Students study how the U.S. shifted focus after the Soviet Union collapsed, examining interventions in the Middle East, responses to terrorism, and engagement with rising powers like China. - **Current Challenges:** Students analyze contemporary issues like climate change (requiring international cooperation), cybersecurity threats, and competition with China, evaluating how historical patterns influence current approaches. **Real-World Application:** When students encounter foreign policy debates—about military intervention, trade wars, climate agreements, or alliances—they can trace how historical experiences and principles influence current decisions and evaluate whether those approaches remain appropriate.
