<span>President Ronald Regan’s goal
for this speech was to see the destruction of the Berlin Wall. However, it was not just the destruction of
the wall that President Ronald Regan was calling for. The call for the taking down of the wall was

would have seen the beginning of peace and stability across Eastern Europe,
which is what the goal really was by President Ronald Regan’s saying “Mr.
Gobachev, tear down this wall!”</span>
