Reagan and Thatcher were both closely involved with Mikhail Gorbachev, the former Soviet leader who evolved from adversary to ally. In 1979, she agreed to place U.S. nuclear missiles in Britain amid protests across Western Europe. Her tough line on the Soviet Union earned her the Iron Lady nickname in the Soviet press.
