"eventually the tide of reality will wash away the sand castle of propaganda."
You'd think so, but given that it's progressive, modern Europe, I doubt it. There might be dribs and drabs of pushing back against it, such as has been the case in France (although largely ineffective due to the far left), but I predict that eventually there will be one of two outcomes...
Total surrender (most likely), or a vicious civil war pitting citizens on one side, extremists on the other, and governments that so hinder and block the citizens that downfall is the only logical outcome. The greater European social state, in its desperate want to be inclusive, encompassing, and tolerant to the point of surrender, is no longer capable of mounting an effective defense of itself.
