The document discusses the end of the Cold War. It states that the collapse of the Soviet Union was not due to military force by NATO, as no tanks fired or bombs fell. Mikhail Gorbachev's policies of glasnost (openness) and perestroika (restructuring) in the 1980s allowed criticism of the Soviet government and led to reforms of the communist system. This loss of confidence in communist rule, along with economic stagnation, contributed to the peaceful dissolution of the Soviet Union and end of the Cold War without direct military confrontation.
