Ronald Reagan
When Reagan visited Moscow for the fourth summit in 1988, he was seen as a celebrity by the Soviets. A journalist asked the president if he still considered the Soviet Union the evil empire. "No", he replied, "I was talking about another time, another era". In November 1989, ten months after Reagan left office, the Berlin Wall was torn down, the Cold War was officially declared over at the Malta Summit on December 3, 1989, and two years later, the Soviet Union collapsed.
