Good article. I just want to add: the lesson must be absorbed and learned very fast before somebody will do the same mistake. As a person, who lived on the western side of the wall, I can say that it will always stay in my heart, my memory and mind. 20 years after Berlin Wall Fall, after Iron Curtain Fall I still do not feel myself totally free. I will never do. I’m afraid that the Berlin Wall generation must die before its descendants will feel free.
