What does the author say the world has done to his brother in "My Dungeon Shook"?

Baldwin blames American society for both destroying his father and his brother. "I know what the world has done to my brother and how narrowly he has survived it. And I know, which is much worse, and this is the crime of which I accuse my country and countrymen... that they have destroyed and are destroying hundreds of thousands of lives and they do not know it and do not want to know it."
