Europe is facing divisive challenges on all fronts. It is being torn within by hardening attitudes toward the growing presence not only of Muslim immigrants, but also of citizens. On Monday, demonstrators thronged the streets of Dresden in support of "Patriotic Europeans Against the Islamization of the Occident." On Wednesday in Paris, 12 people were killed, including cartoonists who lampooned the Prophet Muhammad, in the horrific Charlie Hebdo attack.
While the euro tumbles, northern and southern Europe are bitterly at odds over austerity policies and continuing high unemployment. And a newly aggressive Russia is challenging European values on its eastern frontier.
