In his famous 1987 speech at the Brandenburg Gate, President Ronald Reagan called for expanding democracy by tearing down the Berlin Wall. He used rhetorical devices like repetition and appeals to ethos, logos and pathos to persuade Soviet leader Mikhail Gorbachev. Reagan addressed the problems dividing East and West Berlin, proposing solutions like demolishing the Wall to reunite families and spread freedom. His goal was to take steps toward global peace and reunification through democratic values.
