Thanks for the links, backhoe.
The French politicians and the world press are repeating what was said by their fictional counterparts in Jean Raspail's "Camp of the Saints."
Oh, come to think of it, Raspail used the exact words of politicians and pundits sneering at those who questioned the invasion of the Muslims at the invitation of France at the time.
I read that book a long time ago. Current events make that all a little eerie.
