..German authorities appear unable to stop them..
Or, unwilling. Let them try that in traditional red States.

You added "or unwilling". I've been thinking along those lines, too. Germany seems lost to Western Civilization as we know it. We've assumed it was an arrogant unawareness by the EU leaders/ globalists, thinking they can control it.
Why not assume something quite different? The environment in Germany now is such that it takes Nazi-style military forces and extreme restrictions to stop the violence. What's to stop Germany to claim justification to do so, then use their military forces to quell dissent in all those EU countries which have ceded control to the EU elite through allowing the invasion and by too much dependence on EU bankers?
I've stated it many times: This is WW3, and Germany is winning. It does seem that the EU/German powers that be used obviously expected chaos at G20 to begin their military offensive.
President Trump did something very smart by speaking to Poland before going to G20. Poland, Hungary, Romania, Bulgaria, hopefully a few others have got to get out of the grips of the EU and set their own path.
