Germany, which will receive around 130,000 migrants this month alone, is overwhelmed. Signs of crisis and breakdown are everywhere, and there are still hundreds of thousands of migrants in the pipeline. Desperate German (and some European) politicians continue to try to get other European countries to accept more of the million migrants Germany lured to the continent.
So far they've tried two methods.
The first method is appeals to European "solidarity" and European "values". This doesn't work, because those are lofty abstractions, and nobody agrees on their meaning.
The second method is by threatening to withhold EU funds to countries that don't take "enough" migrants. This doesn't work, because it looks like Germany bullying other countries to clean up its mess. It enrages countries which are much poorer than Germany, threatening to gravely damage the EU itself.
There is a third option, although one that, in my experience, German civil servants never consider: Apologize. A short speech for Merkel:
Europe (or the rest of the world), Germany has been a main driver of this crisis. We failed to anticipate a flow of refugees that anyone could have seen was coming. We didn't prepare. We made a decision to ignore Schengen that sent the wrong signal, luring hundreds of thousands more people. We take full responsibility for this problem. But right now, we are faced with a number of refugees which we simply cannot handle. So in the spirit of humility, we apologize for our previous actions and ask for help.
The migrants are not to blame, at least not the migrants who are actually fleeing war and persecution. They should not suffer unduly for our mistake. We ask you to take significantly more refugees. In return, we will agree to tax our citizens to provide a lavish financial aid package that will reduce the financial burden to a minimum. We will also agree to immediately implement and help pay for strict border controls on the EU outer border, to ensure that we do not get further streams of refugees when we can't cope with the ones we already have.
Other nations of Europe (or the rest of the world), please accept our apology and help us out. We'll remember it the next time you need a favor. That is solidarity.
Maybe it will work, maybe not. But it would be a big improvement on threats and abstractions.
