It would be simplistic to say that Divine Providence caused the fall of Communism. In a certain sense Communism as a system fell by itself. It fell as a consequence of its own mistakes and abuses. It proved to be a medicine more dangerous than the disease itself. It did not bring about true social reform, yet it did become a powerful threat and challenge to the entire world. But it fell by itself, because of its own inherent weakness.
--Pope St. John Paul II
