Anna Sauerbrey offers an optimistic perspective on the actual outcomes (NYT):
For all its shortcomings, Europe has actually managed the crisis quite well, in practice. Its external borders are stronger, and better policed and managed. Cooperation with Libya’s border-patrol militias, however ethically suspect, has brought down the numbers crossing from that country to Italy. So has the agreement with Turkey to host migrants in return for financial aid. In 2015, more than 450,000 pleas for asylum were filed; in 2016, about 745,000. So far this year, there have been only 68,000.
According to figures by the German Federal Agency for Migration and Refugees, only about a quarter of those applying for asylum in Germany in 2018 are already registered in another European country. This means that the C.S.U. risked blowing up the government to push through a regulation that applies to about 100 individuals a day, scattered over all of Germany’s points of entry.
But she is pessimistic about the politics:
Whatever respite Germany may have gained this week is offset, and then some, by the arrival of a new and frightening political dynamic. Mr. Seehofer succeeded by going nuclear; chances are, he won’t be the last. The politics of fear and menace may be here to stay, undermining the foundations of democracy. In sound democracies, policies are the results of compromise between parties representing a majority of the voters. Through the politics of artificial crisis, minorities take the system hostage. They create policies redeeming fictional problems for fictional majorities.
Recommended, this is one of the better takes on the problem I have seen.
