I think that part of the paralysis that is gripping the EU government in general and the Germans in particular is that a basic assumption of their form of governance is being challenged: information control doesn't work. The government takes an official stance on an incident, the media trumpet the party line faithfully and repetitively, slick public relations campaigns, advertisements, appeals to authority in the persons of media celebrities - and it isn't working.
This flies in the face of quite a few unchallenged maxims of modern social control, and the answer usually given is typically statist: what we need to address this failure is more control, especially of alternate means of communication such as the Internet. That didn't work even in the most extreme case of the Soviet Union, where such monolithic control was possible and there was no Internet: samizdat found its ways even if it turned out to be mimeograph machines. In Nazi Germany there still was underground radio despite a death sentence for being caught listening to it.
Information control doesn't work, and that is incredibly threatening to people whose power depends on it. Were every newspaper, television commentator, and Internet journalist in Germany to declare the next Islamic terrorist attack was caused by Lithuanian Mennonites, it would not stop the whispers.
And I might point out as well that the apparently universal horror with which the ascension of Donald Trump is regarded in all the "proper" European media is a perfect example of this phenomenon. It's unanimous, all right-thinking people know the fellow is awful, so why would anyone be silly enough to vote for him? There's quite a bit of two-penny psychiatry involved in attempting to understand the mental pathologies of people who don't sway to that tune when in fact, we're simply not listening to the lies. The problem resides with the liars, not with their intended victims, and the liars don't get it and likely never will.
Do not be misled into accepting the narrative that most Europeans want to have their homelands over-populated with incongruous new arrivals. Most Europeans are simply intimidated by their own pseudo-intellectual betrayers' version of the "politically correct" fantasy that people are interchangeable--the same idiocy that drives the Clintons, Obamas and the like.
There, as here, are two groups that feed off that fantasy, and correspondingly manage to keep most other folk silent--intimidated and silent. One group are those business interests, which put immediate profit ahead of patriotism.
The other group are the compulsion driven neurotics, who for one reason or another, simply cannot tolerate the realization that peoples, as individuals, differ;--that we are all unique, and should be respected for our particular unique qualities--not artificially mixed up in an effort to validate a Leftist/humanist pipe dream.
Because Donald Trump has defied the "politically correct" conventions, that were strangling analysis of real problems in Western countries; because of his rise in doing just that, there is now more hope for a Western reawakening than there has been in decades.
The ultimate issue, both here and in Europe, is whether we--the people of each nation--dare again to be unique; dare, again, to honor our heritages and the noble figures in our respective histories, who helped to develop the impressive cultures of our respective nations. Those cultures, now being trashed by crack-pots), reflect the respective but cumulative struggles of those nations, over the past twelve hundred or so years.
