"I don't think much of a man who is not wiser today than he was yesterday.
  — Abraham Lincoln"

Similarly, the perfection-lover in the wise President Gorbachev says: "Well, suppose we made mistakes. So what? It is better to rectify them than sit and wait."
"Am I not destroying my enemies when I make friends of them?
  — Abraham Lincoln"

President Gorbachev illumines his adversaries instead of destroying them. In this inimitable way, he and his friends, both new and old, walk, march and run towards the same destination: a oneness-peace-world.
