Should the EU evolve into the United States of Europe?

Non lo so.

Yes, but only if the merging has consensus and after a reformation of Eu's goverment system

Yes, but still granting self governance to constituent countries

It depends on which terms and conditions

Yes, as long as no country tries to take over the others

No, this would steal each nation of their sovereignty

Yes, but not how it is now.

Yes in some aspects, EU countries should have their own devolved power, similar to the Scottish Parliament

Yes, if it is socialist.

Yes, with Germany at the center of the EU

Only when and if it and its people are ready

Yes, and abolish all national borders.
