It doesn't happen very often in this world, but every now and then, the forces of evil really can be turned back. The Berlin Wall was built and maintained by such forces, and its crumbling was truly a moment to savor.
the "tear down this wall" phrase was the subject of INTENSE debate within the State Dept. and CIA before Reagan went to Germany. All the self-anointed "clever" people thought that saying those words would be a bad idea. Thank God we had a president at that time with the wisdom to ignore the self-anointed "clever" people.
