Early American Expansion and Isolationism
📌 For the first 70 years, the US expanded across North America, resulting in the slaughter of indigenous peoples.
🤔 Early American leaders were deeply divided on whether to expand beyond the Pacific and Atlantic oceans, leading to strong anti-imperialist opposition in Congress.
🏛️ The Industrial Revolution concentrated power in the federal government, enabling expansionist presidents like William McKinley to push influence abroad more easily.

Transition to Global Power (1898 Onward)
💥 The turning point was the Spanish-American War in 1898, leading to the acquisition of Puerto Rico, Guam, and the Philippines.
🌐 This period saw rapid acquisition of territories (e.g., Hawaii 1898, Panama Canal Zone 1903) establishing the US as a truly global power.
🌍 President Wilson attempted to remake global politics after WWI with the League of Nations, though Congress ultimately blocked US entry.

Post-WWII Global System Establishment
🛡️ WWII left the US as the only major power unscathed and possessing atomic weapons, allowing it to set the terms of the post-war peace.
🤝 Key institutions like the United Nations and the Bretton Woods Agreement (creating the World Bank and IMF) were established to promote peace and financial stability.
🛑 The US adopted a strategy of "containment" against the Soviet Union, leading to constant global intervention, military buildup, and alliances like NATO.

Post-Cold War Continuity and Divergence
➡️ After the Cold War, Presidents Bush and Clinton maintained the global system, keeping NATO and military alliances active to manage global affairs.
💸 A major theme of the post-Cold War era has been the expectation that allies should pay more for US protection.
🔄 Donald Trump's rhetoric signals a potential sharp divergence from the post-1945 foreign policy consensus, questioning the value of alliances like NATO and free trade.

Key Points & Insights
➡️ The shift to global power was driven by industrial economic growth concentrating federal power and key military victories like the Spanish-American War in 1898.
➡️ The post-WWII global structure (UN, IMF, NATO) was explicitly designed to prevent the recurrence of great power conflict and economic collapse.
➡️ US commitment to global management was maintained even after the Soviet threat diminished, turning Cold War infrastructure into a permanent fixture of US foreign policy.
