“Paul said world powers “could have done a better job drawing up these country lines” after World War I: “
A huge part of the borders of Africa, the Middle East and Asia are drawn based on European colonial priorities. They are responsible for many countries containing groups that really should be in separate countries and others case where an ethnic group is split into more than one country.
This has contributed greatly to instability across that part of the world.
That was the intent IMHO. Rather than walk away from their colonies and accept that era was over, the colonial powers intentionally set up permanent instability zones that they could easily dominate even if they could no longer own them outright. Such a great idea, eh?
