As successive European countries impose strict border controls, it’s like a series of watertight doors closing along the route that “Syrian” “refugees” take to get to Germany. When one state blocks the flow and slows it to a trickle, the migrants back up at that border, forcing the host country to follow the same strategy.

This video is a skillful combination of drone and ground-level footage, with no voice-over or commentary:
