That is the I evitable flaw in the EU bureaucrats plan. It would have to come to that at some point.
My prognostication as I have watched this move towards this point for the last fifteen years or so has been that the result of the flash point will turn out for the bureaucrats the same way things turned out for Louis XIV. And then the Muslims will be swept out of Europe in an entirely predictable genocidal war, using nukes if required.
Louis XIV WON! You are thinking of his far more modern and democratic great grandson (i believe) named Louis XVI who was hauled away to the guillotine by Lafayette’s cousins.
