Reagan's Berlin Speech in 1987 challenged Gorbachev to reform and symbolically tear down the Berlin Wall, which divided the Soviets from the United States.

Explanation:

In a speech at the Brandenburg Gate, just at the Berlin Wall on June 12, 1987, President Reagan called on Soviet Union leader Mikhail Gorbachev to demolish the wall as a symbol of his desire to increase freedom in Eastern Europe. On November 9, 1989, the East German government removed all restrictions on travel by East Germans abroad, which meant the end of the wall.

Reagan made the speech despite protests from the Department of State and the National Security Council. Former national security adviser (and future foreign minister) Colin Powell was one of the Reagan administration's biggest opponents to the speech.
