The interior ministers' dispute gives a foretaste of what would happen in the EU if a really large number of refugees from Afghanistan came to Europe in the near future.
As it is now with the question of how to define the group of those directly in need of protection, the picture would probably look like again: restrictive Eastern Europeans against more receptive governments in the West.
The EU has not used the time since 2015 to reform its asylum system, although it has become clear that it is legally and politically unsustainable.
In the common area of freedom of movement, rules are required that everyone respects, otherwise the smugglers are the laughing third parties.
The fact that the EU was divided at the time was due to the German policy of open borders, which ultimately nobody in Europe wanted to support.
The (outgoing) Federal Minister of the Interior is now saying that it is not wise to talk about admission quotas because that could offer an incentive to flee.
This indicates a certain learning effect in Berlin, but if in doubt it will not be enough.
The (presumably also outgoing) Foreign Minister is in the region where there is little will to deal with the consequences of the Western failure in Afghanistan. The moment of truth will strike for the new federal government, because the land route from Afghanistan to the borders of Europe is long.
