What role did President Reagan play regarding the Berlin Wall?

President Reagan's visit to the Berlin Wall in 1987, where he famously called on Soviet leader Mikhail Gorbachev to "tear down this wall," played a critical role in advocating for the wall's removal. This speech symbolized a strong stance against the division of East and West Berlin and the broader ideological divide of the Cold War. Reagan's remarks were not just a call for physical removal but represented a larger push for the end of oppressive regimes in Eastern Europe. His visit highlighted the U.S. commitment to freedom and democracy, significantly influencing public perception and the political landscape of the time. This act positioned him as a key figure in the eventual fall of the Berlin Wall in 1989, which marked a pivotal moment in the ending of the Cold War.
