A Guerra Fria começou após a Segunda Guerra Mundial, dividindo o mundo em duas esferas de influência.O mundo se dividiu entre duas superpotências: os Estados Unidos, liderando o bloco capitalista, e a União Soviética, liderando o bloco comunista.Vamos examinar os eventos cruciais que marcaram o início da Guerra Fria.Em 1947, a Doutrina Truman estabeleceu uma política clara de contenção à expansão do comunismo.O símbolo mais marcante desta divisão foi o Muro de Berlim, construído em 1961, separando a cidade em Oriental e Ocidental.Esta divisão do mundo estabeleceu o cenário para décadas de tensão e competição entre as duas superpotências.The arms race began when the Soviet Union developed its first atomic bomb in 1949.Both superpowers rapidly expanded their nuclear arsenals throughout the 1950s.The nuclear stockpiles grew from just a few hundred weapons to tens of thousands by 1960.The space race began with the Soviet launch of Sputnik in 1957, shocking the Western world.The Soviets achieved several early victories in space exploration.The United States worked to catch up, with achievements like John Glenn's orbital flight.This competition drove remarkable scientific progress in many fields.By the 1980s, the Soviet Union faced severe economic challenges.In 1985, Mikhail Gorbachev became the leader of the Soviet Union and recognized the need for major reforms.Gorbachev introduced two major reform programs: Perestroika, focused on economic restructuring, and Glasnost, promoting political openness.Despite these reforms, the Soviet economy continued to struggle, and political tensions increased.The situation reached a critical point in 1989 with the fall of the Berlin Wall, symbolizing the beginning of the end for Soviet control in Eastern Europe.By 1991, the Soviet Union began to break apart as various republics declared independence.The dissolution of the USSR marked the end of the Cold War and the Soviet communist system.
