Why does France keep being attacked?

The Rotten Heart of Europe

And a forecast by Stratfor (October 2015)

• In Europe, the process of integrating foreigners will remain problematic, especially because migrant workers tend to have fewer job opportunities than their native peers.
• Right-wing parties and groups will continue to resist arriving foreigners, attack migrant shelters and protest immigration policies.
• Although immigration can somewhat mitigate the effects of a shrinking and aging population, it cannot reverse it, nor will all EU members attract foreigners to join their workforces.
