Actually the first step should be to get rid of treasonous Merkel and her crew that wants to wipe out Germany and its culture, and replace them with AfD.
Merkel and her party are the problem, the muslims are the symptoms.
So the $64K questions is... are the germans prepared to do that? Doesn’t seem like it.
Thus, in the final analysis, perhaps the real problem are the german people themselves... and that French guy was right, “People get the government they deserve”.
