"Mr. Gorbachev, open this gate. Mr. Gorbachev, tear down this wall!" Famous speech by Reagan made in 1987, two years before the fall of the German Wall and one year before USSR fell apart, was an incredibly powerful statement to the tension between the two superpowers. However, after USSR ceased to exist, the diplomatic relationships between Russia and USA improved greatly. Pictured here, leaders of the two nations reunite. Life Photo Collection, 1992.
