Ben Ferencz
This video is a recent interview from 60 Minutes with a Ben Ferencz, an extraordinary person who has now turned 100. As a young man, he was a prosecutor at the Nazi war crimes trials in Nuremberg just after WWII. I should warn you, there is a brief moment of film from the war, showing actual brutal murders. I hesitated posting it because that part is so difficult. Avert your eyes, or don't watch at all, if you must. Just know: evil doesn't go away just because we don't look. Quite the opposite. It only grows stronger when we don't look.
But the overall message is optimism. Despite the horrible things this man has seen, he's stunningly optimistic. Some would call him naive, and he talks about that. I think you may find something here to inspire you. I did.
Do not lose your optimism, your hope that things can improve. Especially in these times when our own country is being so evil. If this man can remain optimistic, we all can have hope.
Just be braced for some of the worst of humanity too. And have courage.
