Things come in waves

The EU is currently continuing it's expansion east, doubling in size. I do wonder how long it will last, and if we will see an equal and opposite swing the other way just like CCCP and Yugoslavia did.

In 30-50 years time will we see a disentanglement effort and eventual peaceful breakup and separation?

I for one think the EU is something quite different from past efforts to integrate states. How things will fair after China and India change the world-trade map will be interesting to see, fingers crossed the EU lasts ;)
