James Baldwin said this quote

...when the black populations of the world have a future, so will the Western nations have a future-and not till then. But the terrible probability is that the Western populations, struggling to hold on to what they have stolen from their captives, and unable to look into their mirror will precipitate a chaos throughout the world which, if it does not bring life on this planet to an end, will bring about a racial war such as the world has never seen, and for which generations yet unborn will curse our names forever.
