The problem with Africa is that most of the nations are artificial. The Europeans just drew some lines on the map. Now, the only thing that might incline these people to work together with minimal conflicts is the prospect of seeing their children eat food and the prospect of seeing their children learn something at school. But these are the common people, not the people in power, they would rather have their own power base. They might think of carving more nations out of Africa as is already seen in the case of South Sudan (created on 9th Jul 2011) and Azawad (declared on 6th Apr 2012). Even though there will be economic development in Africa, I doubt the lives of the people will drastically improve. Conflict is embedded in human nature. I think it's wishful thinking to suggest that their wouldn't be world wars in the future. And it's precisely the lack of resources which will cause these wars/conflicts. Lets say you have a room and you put two humans in it with one apple. They will probably share it. Now lets say you put 10 humans and an apple, what do you think will happen ? Saying that there wouldn't be large scale wars in the future is incorrect. Agreed. Both nations will have pretty awesome navies by 2035.
