One of the big differences between the Europeans and Americans is that americans believe in self-government. That is, that the right to govern descends from the voluntary permission of the people. Europe is just the opposite. It has always been a group of societies where some big-shot rules the masses by some form of "divine right". The big-shots may change, but the overall idea remains the same.
Ayn Rand said it best "Europeans may rebel against their government, and may even hate it. But they never question government's right to rule over them. When they rebel, it is rather like a dependent slave who hates and flees from one master, only to seek a better master somewhere else."
The pro-EU leaders are stacking the deck against the citizens of Europe. The people are being made to vote repeatedly on issues of conceding power to the EU. Last year, Ireland rejected by overwhelming numbers an expansion of the EU to include Turkey. That vote was effectively nullified when the issue came up for a vote again this year. The outright propaganda aimed at the uninformed led to the expansion's passage on the second time around. Had the issued failed this year, no doubt it would have come up for another vote next year, and every year after until it did pass.
EU expansion is a battle of attrition. Those who disagree are being steamrolled and exhausted into conceding.
