Way too late for France and most of western Europe.
They have already let in their future and it is Islam.
They will submit or die.
That is Islam.
You know, this wasn’t the first time France or Europe was invaded by the Muslim hordes. Don’t forget the Crusades. And the Muslims were ultimately driven out. Make no mistake, it may take a little while, but nationalism will have a massive resurgence, enough to drive the Muslims out, and hopefully purge the leftists as well. While they’re at it, they might as well restore the monarchy. It is ultimately better that way.
