In 1979 a socialist government took power in Afghanistan but was hard-pressed and requested military help from Moscow. The Soviet army intervened to support the socialists, but found itself in a major confrontation. The presidency of Ronald Reagan in the United States was fiercely anti-Soviet, and mobilized its allies to support the guerrilla war against the Soviets in Afghanistan. The goal was to create something akin to the Vietnam War which would drain Soviet forces and morale. When Mikhail Gorbachev became the leader of the Soviet Union in 1985, he sought to restructure the Soviet Union to resemble the Scandinavian model of western social democracy and thus create a private sector economy. He removed Soviet troops from Afghanistan and began a hands-off approach in the USSR's relations with its Eastern European allies. This was well received by the United States, but it led to the breakaway of the Eastern European satellites in 1989, and the final collapse and dissolution of the USSR in 1991. The new Russia, under Boris Yeltsin, was no longer communist.
