I don't think group conflict is a very well solved problem. I don't think we are able to achieve that, either. What I can see is when there is a group conflict, after the extra energy is vented, and the groups involved are still there, they look for mutual interests and fall back to that base and go from there. Race issue is one big example of this. We do have some system works better than others. But putting it into a bottle with absolute right mark on it may not be the best way to go under current situation. I'm probably biased since I'm Chinese. I agree with most part of this report. The author did a lot of good homework. But I think his thoughts to work out those strategies need some update to better fit in the world today and tomorrow. There are similar parts and there are different parts.
