Along with British Prime Minister Margaret Thatcher, Reagan harshly criticized the Soviet Union on ideological and moral terms. In 1983, Soviet Union fighter planes shot down a Korean Air commercial passenger plane, killing all 269 passengers, including a US congressman. This prompted a harsh diplomatic and economic response by President Reagan. Under the Reagan Doctrine, the United States provided arms, training, and financial aid to anti-communist movements around the world, including Islamist Mujaheddin forces in Afghanistan. The “Reagan Doctrine” offered support to anti-communist opposition in central Europe and worked against socialist and communist governments. During his presidency, Reagan implemented the Strategic Defense Initiative, which attempted to create a missile-defense system. Critics challenged this as technologically unfeasible. Key Terms
