I think the strength of euroskepticism is the consequence of a lie. The truth is that the whole point of the EU is to get rid of nation states, but in the last 20 or so years, the EU lied about this in order to spare the feelings of nationalists. And no matter how gentle that lie was, we are now paying its price.
The idea of the EU emerged after two World Wars, when nationalism and the confrontation between nation states devastated the continent. You should not be surprised that Churchill, a man whose patriotism cannot be questioned, was an advocated of the strong integration: a United States of Europe.
