Ten years ago, John Paul II wrote that World War II appears with evermore clarity as a "suicide of humanity". Each time a totalitarian ideology crushes man, humanity as a whole is seriously threatened. With the passing of time, memories do not have to fade; rather, they must be a stern lesson for this and future generations. We have the responsibility of reminding especially youth of the forms of unprecedented violence that can lead to contempt for men and women and the violation of their rights.
