This submission has been removed because it involves current events. To keep from discussion of politics, we have a 20-year rule here. You may want to try /r/ask_politics or another current-events focused sub.

To be clear, the question on the formation of the USA is fine, but asking about applying those conditions to modern Europe, and especially speculating on how that might work is off limits in this sub, per the rules against current events ("20-year rule") and speculation.
