Right now she is third in the list of people most destructive to Germany behind Marshal Zhukov and Bomber Harris and she's moving upward fast.
She has chosen stupidly in the last year in throwing open the gates to the armies of Hijrah, but she is not permanently and ineradicably stupid.
Germany has had a mutually beneficial relationship for decades with Turkish "guest workers" who were respectable people, not social parasites, not predators. Mutti Merkel is rapidly realizing that this is a whole 'nother thing. Merkel's learning curve may be steep, but she will --- I predict --- get rid of the predators and parasites. I hope she can still extend welcome to the true innocents and allies: the Christians, the Yazidis and the tough, anti-ISIS Kurds.
