Ronald Reagan's speech at the Brandenburg Gate, West Berlin (1987)

Chancellor Kohl, Governing Mayor Diepgen, ladies and gentlemen: Twenty-four years ago, President John F. Kennedy visited Berlin, speaking to the people of this city and the world at the city hall. Well, since then two other presidents have come, each in his turn, to Berlin. And today I, myself, make my second visit to your city.

Behind me stands a wall that encircles the free sectors of this city, part of a vast system of barriers that divides the entire continent of Europe. From the Baltic, south, those barriers cut across Germany in a gash of barbed wire, concrete, dog runs, and guard towers. Farther south, there may be no visible, no obvious wall. But there remain armed guards and checkpoints all the same -- still a restriction on the right to travel, still an instrument to impose upon ordinary men and women the will of a totalitarian state. Yet it is here in Berlin where the wall emerges most clearly -- here, cutting across your city, where the news photo and the television screen have imprinted this brutal division of a continent upon the mind of the world. Standing before the Brandenburg Gate, every man is a German, separated from his fellow men. Every man is a Berliner, forced to look upon a scar.

Today I say: As long as this gate is closed, as long as this scar of a wall is permitted to stand, it is not the German question alone that remains open, but the question of freedom for all mankind. Yet I do not come here to lament. For I find in Berlin a message of hope, even in the shadow of this wall, a message of triumph.

in the West today, we see a free world that has achieved a level of prosperity and well-being unprecedented in all human history. In the Communist world, we see failure, technological backwardness, declining standards of health, even want of the most basic kind -- too little food. Even today, the Soviet Union still cannot feed itself. After these four decades, then, there stands before the entire world one great and inescapable conclusion: Freedom leads to prosperity.

And now the Soviets themselves may, in a limited way, be coming to understand the importance of freedom. We hear much from Moscow about a new policy of reform and openness. Some political prisoners have been released. …

There is one sign the Soviets can make that would be unmistakable, that would advance dramatically the cause of freedom and peace. General Secretary Gorbachev, if you seek peace, if you seek prosperity for the Soviet Union and Eastern Europe, if you seek liberalization: Come here to this gate! Mr. Gorbachev, open this gate! Mr. Gorbachev, tear down this wall!
