My opinion, the EU should have remained simply a free trade organization rather than trying to become a supra-national government. There really is no such thing as " European " . The countries in Europe have many distinct and different outlooks which simply cannot be ignored. If you want an argument, tell a Frenchman and a Englishman that they are the same and they will know you are a fool. Their histories and outlooks are so different in many respects. Think about Napoleon Bonaparte. He remains a hero in France with a huge mausoleum celebrating the approximate fifteen years of general war he brought upon the continent of Europe. To the British he simply was a warmongering dictator that brought ruin. We tend to think of World War 1 ( 1914 - 1918 ) as the first global war but in reality historians look upon the Napoleonic Wars which engulfed Europe from 1803 - 1815 as a truly global war since not only Britain but Austria, Russia, Prussia ( Germany ), Italy ( Papal states ), Spain and more were involved and since Britain, France, Spain had global empires at the time, they fought a global war. It even involved the fledgling United States since Britain and France both raided American shipping and the United States had its second war against Britain, what we call The War of 1812, due mainly to the depredations of the Royal Navy against American shipping.
So, in conclusion, the people of Europe should have stayed with the original impulse of the European Steel and Coal treaty of 1955 and left it at that rather than bureaucratic and undemocratic monster the EU has become. Trying to mix Greeks and Germans together in a government is a recipe for disaster. The proof is present day news. My $0.02.
