"The world under heaven, after a long period of division, tends to unite; after a long period of union, tends to divide." - Romance of the Three Kingdoms It's really is kind of inevitable that this will happen. We've had unprecedented peace and prosperity for many decades. Everyone is getting rich and fat (relatively speaking) and more capable of projecting their power and protecting their interests. The unification of Europe (rebuilding, euro EU), the rise of China, the nuclearization of North Korea, etc. There is no governing body above states - its an anarchic system in that regard. It's just not possible to achieve full globalization and keep it. We'd need something to fundamentally change the game like competition with another world. Im not sure if you've noticed but the world order has been degrading since the 90's.
