They were okay when they were just an in-transit way station for the influx outbound to Germany. Now that Germany has said “screw it” and tightened up, they realize that the “buck stops there [Austria].”

Hard to imagine a financially-astute, conservative German population would stand idly by and allow the unruly Syrian mobs to takeover their beautiful country.
