				By the late 1980s, the Soviet Union was surrounded by hostile states, while having to cope with economic woes, discontent in Poland, and a high tech arms race with the United States. Mikhail Gorbachev, the new Soviet leader, responded with huge political and economic reforms. In 1989, he allowed elections and revolutions to overthrow the communist regimes in eastern Europe.
