"For African migrants, ‘extreme vetting’ from U.S. to Europe slams the door shut".

Maybe if the door was slammed shut a long time ago we would have have had this human tide wash over Europe, maybe this army of young men would have stayed in their countries and tried to make a go of them.
Common sense dictates this "camp of the saints" must stop.  Read the book by Jean Raspail.  This human invasion was predicted by him in a best selling novel over 40 years ago, and it's coming true in front of our eyes.
