The well-spring of the millions and millions of so-called “refugees” currently invading Europe (excluding Russia of course) and demanding entry into other nations that fit into their desired pattern of those being dominated by the politically liberal left are not really motivated by an understandable fear of the civil war in Syria. Or the war being fought with the Kurds. Or the war being prosecuted by ISIS and fighting both Iraqi and Iranian militias, with the current addition of Russian air and ground forces.
Of course, listening to those who are among those on the extreme left, the real source of this “crisis” is the imperialistic behavior of the United States and Europe and their behavior vis-à-vis the Middle East and the rest of the Islamic world.
