The 1980s (pronounced "nineteen-eighties", shortened to "the '80s" or "the Eighties") was a decade that began January 1, 1980 and ended December 31, 1989. The decade saw a dominance of conservatism and free market economics, and a socioeconomic change due to advances in technology and a worldwide move away from planned economies and towards laissez-faire capitalism compared to the 1970s. As economic deconstruction increased in the developed world, multiple multinational corporations associated with the manufacturing industry relocated into Thailand, Mexico, South Korea, Taiwan, and China. Japan and West Germany saw large economic growth during this decade. The AIDS epidemic became recognized in the 1980s and has since killed an estimated 39 million people (). Global warming became well known to the scientific and political community in the 1980s. The United Kingdom and the United States moved closer to supply-side economic policies, beginning a trend towards global instability of international trade that would pick up more steam in the following decade as the fall of the USSR made right-wing economic policy more powerful. The final decade of the Cold War opened with the US-Soviet confrontation continuing largely without any interruption. Superpower tensions escalated rapidly as President Reagan scrapped the policy of détente and adopted a new, much more aggressive stance on the Soviet Union. The world came perilously close to nuclear war for the first time since the Cuban Missile Crisis in 1962, but the second half of the decade saw a dramatic easing of superpower tensions and ultimately the total collapse of Soviet communism. Developing countries across the world faced economic and social difficulties as they suffered from multiple debt crises in the 1980s, requiring many of these countries to apply for financial assistance from the International Monetary Fund (IMF) and the World Bank. Ethiopia witnessed widespread famine in the mid-1980s during the corrupt rule of Mengistu Haile Mariam, resulting in the country having to depend on foreign aid to provide food to its population and worldwide efforts to address and raise money to help Ethiopians, such as the Live Aid concert in 1985. Major civil discontent and violence occurred, including the Angolan Civil War, the Ethiopian Civil War, the Moro conflict, the Ugandan Bush War, the insurgency in Laos, the Iran–Iraq War, the Soviet–Afghan War, the 1982 Lebanon War, the Second Sudanese Civil War, the Lord's Resistance Army insurgency, and the First Nagorno-Karabakh War.
