to "save" South Vietnam from conquest, which many Americans feared would lead to Communist dominance in the entire region. The Vietnam War lasted many years, but most Americans felt the North Vietnamese would be defeated in time. Despite American technological and military superiority, by 1968, the war showed no signs of ending and most Americans wanted U.S. forces to end their involvement. The U.S. undercut support for the North by getting the Soviets and Chinese to stop supporting North Vietnam, in exchange for recognition of the legitimacy of mainland China's Communist government, and began withdrawing troops from Vietnam. In 1972, the last American troops left Vietnam and in 1975 South Vietnam fell to the North. In the following years Communism took power in neighboring Laos and Cambodia. By the 1970s global politics were becoming more complex. For example, France's president proclaimed France was a great power in and of itself. However, France did not seriously threaten the U.S. for supremacy in the world or even Western Europe. In the Communist world, there was also division, with the Soviets and Chinese differing over how Communist societies should be run. Soviet and Chinese troops even engaged in border skirmishes, although full-scale war never occurred. The last great armed conflict of the Cold War took place in Afghanistan. In 1979, Soviet forces invaded that country, hoping to establish Communism. Muslims from throughout the Islamic World travelled to Afghanistan to defend that Muslim nation from conquest, calling it a Jihad, or Holy War. The U.S. supported the Jihadists and Afghan resisters, despite the fact that the Jihadists were vehemently anti-Western. By 1989 Soviet forces were forced to withdraw and Afghanistan fell into civil war, with an Islamic fundamentalist government, the Taliban taking over much of the country. The late 1970s had seen a lessening of tensions between the U.S. and Soviet Union, called Détente. However, by the 1980s Détente had ended with the invasion of Afghanistan. In 1981, Ronald Reagan became President of the United States and sought to defeat the USSR by leveraging the United States capitalist economic system to outproduce the communist Russians. The United States military was in a state of low moral after its loss in the Vietnam War, and President Reagan began a huge effort to out-produce the Soviets in military production and technology. In 1985, a new Soviet leader, Mikhail Gorbachev took power. Gorbachev, knowing that the Soviet
