Thirteen years later the Berlin Was was erected by the Communists. But because of the efforts of Ronald Reagan--the West won the Cold War and the Berlin Wall was demolished.
"Yes, across Europe, this wall will fall," Reagan said in his 1987 Tear-Down-This-Wall speech, "For it cannot withstand faith; it cannot withstand truth. The wall cannot withstand freedom."
Imagine what Europe would look like if the Anglo-American invasion of Nazi-occupied France never occurred. There would be no freedom in Europe today.
