Well, the EU is not one country and probably never will be. One of the most important countries has already left, euroskepticism is a major political force in many of the remaining ones, the idea of “ever closer union” seems to be dead, some natural future members (Turkey, Serbia) are indefinitely stalled, and even mildly authoritarian members like Hungary and Poland (which, btw, are infinitely more liberal and democratic than Cuba or Venezuela) are constantly in conflict with the central institutions. I doubt there will ever be even an EU-like structure encompassing Latin America, but even if there is, that would be a far cry from becoming a united sovereign state.
