Origins and Ideological Conflict
📌 The Cold War began after WWII, framing a global ideological struggle between Communism (USSR) and Capitalism (US), characterized by proxy wars, nuclear stockpiling, and espionage.
☭ The rise of the USSR followed the Bolshevik Revolution of 1917, establishing a one-party state under Lenin, which transitioned to Stalin's industrial superpower status at a massive human cost (over 10 million killed in famine).
💰 In contrast, Western capitalism struggled with flaws like price fixing and the Great Depression, leading Woodrow Wilson to promote political self-determination and the failed League of Nations.

Post-War Division and Containment
🏛️ The US sought post-war security through institutions like the United Nations, the World Bank, and the IMF, which Stalin largely rejected as promoting capitalism.
🚧 Stalin established a buffer zone in Eastern Europe, securing control through force (e.g., the Czechoslovakian coup in 1948) and leading Churchill to declare an "Iron Curtain" descending across the continent.
🛡️ The US responded to Soviet aggression (Iran crisis, pressure on Turkey) with the Truman Doctrine and the policy of containment, aiming to let the Soviet system collapse internally.

The Escalation of Global Competition
🚨 The CIA was established in 1947 to conduct covert operations, such as secretly funding anti-communists in Italy in 1948 to prevent the popular Italian Communist Party from winning elections.
💶 The Marshall Plan (1948) injected nearly $13 billion (equivalent to $130 billion today) in aid to reconstruct Europe and undercut communist appeal, which Stalin forbade Eastern Bloc nations from accepting.
💣 The nuclear arms race intensified after the USSR tested its own atomic bomb in 1949; President Truman then announced the development of the far more powerful hydrogen bomb in 1950.

Key Crises and Shifting Strategies
💣 The Korean War (1950-1953), triggered by Kim Il Sung's invasion, proved containment could work, but established the precedent that nuclear weapons would not be used in proxy conflicts (Truman fired MacArthur for advocating their use).
💥 Eisenhower adopted a strategy of preparing for "all-out nuclear war" as the best deterrent, viewing nuclear weapons as usable on "strictly military targets."
🧱 Khrushchev's challenge to Berlin led to the Berlin Blockade (1948), countered by the Berlin Airlift, and later the construction of the Berlin Wall in 1961 to stop massive defections (2.7 million from East Germany since 1949).

The Brink of Nuclear War and Détente
☢️ The Cuban Missile Crisis (1962) brought the world closest to nuclear war after Khrushchev placed nuclear missiles in Cuba; the crisis ended when the US agreed to remove Jupiter missiles from Italy and Turkey.
🧊 The crisis led to the establishment of the Hotline between Moscow and Washington and the development of Mutually Assured Destruction (MAD) policy, emphasizing targeting cities for maximum casualties.
🤝 The SALT I Treaty (1972) between Nixon and Brezhnev marked the beginning of Détente, easing tensions and freezing the number of ballistic missiles on both sides.

Internal Strains and the End Game
📉 Brezhnev's era saw stagnation, while Western Europe flourished (foundation of the European Union), making the disparity between East and West increasingly obvious.
💥 Détente collapsed following the Soviet invasion of Afghanistan in 1979, leading Carter to boycott the Moscow Olympics and announce the Carter Doctrine asserting force to protect Persian Gulf oil.
💪 Ronald Reagan pursued "Peace through Strength," dramatically increasing the US defense budget (nearly doubling it between 1980 and 1985) and proposing the Strategic Defense Initiative (SDI), or "Star Wars," to bankrupt the USSR.
🕊️ Mikhail Gorbachev, recognizing systemic failure, introduced Perestroika (restructuring) and Glasnost (openness), leading to democratization and the end of the Brezhnev Doctrine enforcement.

Collapse of the Eastern Bloc
📉 Gorbachev's reforms spurred democratic revolutions across Eastern Europe in 1989, culminating in the fall of the Berlin Wall on November 9th.
💥 The failed August Coup in 1991 by Communist hardliners against Gorbachev solidified the political shift; Boris Yeltsin, elected President of Russia, led the charge for dissolution.
🔚 On December 25, 1991, Gorbachev resigned, officially terminating the USSR, ending the 40-year conflict.

Key Points & Insights
➡️ The Industrial Revolution created the economic inequality that fueled Marxism and the subsequent Communist movements.
➡️ The Truman Doctrine based on containment became the foundational US strategy for dealing with Soviet expansionism after WWII.
➡️ The Cuban Missile Crisis was averted by Vasily Arkhipov’s refusal to authorize a nuclear torpedo launch, highlighting the immense role of human decision at critical moments.
➡️ Gorbachev's policies of Glasnost and Perestroika, inspired partly by the cover-up of the Chernobyl disaster in 1986, ultimately led to the collapse of Soviet control.
