My dad was a Marine. He was one of the Montford Point Marines. Those are the equivalent of the Tuskegee Airmen for Marines. He's a tough tough guy. When I was 15 we had a fight and I didn't speak to him for 10 years.
Ultimately we have just one moral duty: to reclaim large areas of peace in ourselves more and more peace and to reflect it towards others. And the more peace there is in us the more peace there will be in our troubled world.
