I think the EU took a wrong turn when it opened the door to membership to the whole gamut of eastern european countries. The motivations at the time were mainly financial: greedy banks and companies looking for cheap labour zones and potential markets. 

What they conveniently overlooked was the history of political trouble and marginal historical commitment to democracy shown in these states. Now the chickens are coming home to roost all over these eastern states as one after another they swing towards civil unrest and fascism.
