Re history: this depends on who writes it. On the assumption that history decides that Brexit was a disaster, maybe it will blame the voters who wanted to come out of the EU? Or the British Empire, which appears to be the favoured target of a great deal of blame on these boards. Myself, I think William the Conqueror has to share much of the blame, together with the Ancient Romans, who, after all, foisted Christianity on the world, to the extent that a major sect is still based in their home base, running a close second. Or maybe the Celts, those dastardly incomers! They were Europeans too, of course!
