It's going to get worse in the Middle East and Africa. The boundaries of all those countries were set by the old imperial rulers and cut right through ethnic, clan, tribal, religious and language groups. Most of these groups don't get along that well with each other. This is not a recipe for long term peace and stability. It's one of the reasons you have so many strong man rulers instead of democracies because only a dictator type can keep the different groups in line.
Also, you still have the the former colonial powers, China, US, Russia, plus non-state actors, each trying to continue to exploit these countries for their own gain.
