I think so, in the coming 50 years I think we will see a rapid unification of nations all over the world into larger political forms. Already we are seeing Europe and American living standard being lowered by the economic rise in China.
The Ukraine will need the EU to develop its economy and will be the only route to raise living standard for its people. Poland has benefited hugely to EU membership and I'm sure other eastern block countries will be keen to make a similar move. Its already clear those in power in the EU want to cast as wide a net as possible.
