"There may be times when we are powerless to prevent injustice, but there must never be a time when we fail to protest. The Talmud tells us that by saving a single human being, man can save the world. We may be powerless to open all the jails and free all prisoners, but by declaring our solidarity with one prisoner, we indict all jailers. None of us is in a position to eliminate war, but it is our obligation to denounce it and expose it in all its hideousness. War leaves no victors, only victims.
...Mankind needs to remember more than ever. Mankind needs peace more than ever, for our entire planet, threatened by nuclear war, is in danger of total destruction. A destruction only man can provoke, only man can prevent. Mankind must remember that peace is not God's gift to his creatures, it is our gift to each other."
