The worst thing that could have happened, the shoe waiting to drop, was a terror attack at Christmas time in Germany by an asylum-seeker linked to Islamist terror groups. It is just that which took place in Berlin this week.
That the inevitable has now occurred likely seals the political fate of Europe. Public opinion will surely turn decisively against the open-arms refugee policy of German Chancellor Angela Merkel — the most prominent defender of the troubled European project of integration and the free movement of people.
Alternative for Germany party and other anti-immigrant groups are already capitalizing on the incident.
