Ronald Reagan became president in 1981 and took a much more hard-line approach toward the Soviet Union, changing the tone of U.S.–Soviet relations. Leonid Brezhnev’s death in 1982 brought new Soviet leadership, which also helped relations begin to shift. The invasion of Afghanistan had sharply worsened relations earlier, in 1979, rather than marking the early-1980s change asked about here.
