Merkel recovered enough of her political wits, which have historically caused her to move to co-opt opposition and sell herself as the best and safest compromise. In this case, she had the wit to order the reinstatement of border controls and that has appeared to have quieted down a lot of anger.
How well that has worked I don't know. Brad Macdonald's piece below indicates that she lied about the total that would be let in and, in any event, the original number of "only" 800,000 vice 1.5 million will work its magic on German minds as the effects of such an alien presence are felt in actual neighborhoods and in various budgets and (top secret) crime statistics. No longer foreigners walking through distant fields but now "Abdul my neighbor." Can love and harmony be far behind?
The German authorities are lying about and covering up the crimes and primitive behavior of the newcomers. Here's a telling story about that from Macdonald's article:
Across Germany, frustration, uncertainty and anger are welling up. A growing number of Germans are feeling betrayed and want change. They want a leader who will listen to their anxieties, defend their interests, and protect Germany.So Merkel confounded my prediction with ease by a little kabuki kapering at the borders. However, I don't think it will be long before a certain "social percolation" takes place and maybe in the early spring Merkel will come under increased pressure again as the extent of the disaster and the government's lying becomes clearer. Germans are not stupid and certainly not as supine as their government is counting on. Es kommt die Zukunft.
They are totally silent, he said.
In the meantime, I will hew to the sage advice once given to economists: Give them a date or give them a number, but never give them a date and a number.
But Merkel will go. No politician can front such a gigantic, insane social catastrophe and again maneuver herself to some temporary safe space. The numbers are huge and the immigration catastrophe is finally developing some very sharp edges.
