The fact that the Russian foreign minister was not allowed to travel to Poland for an OSCE meeting is not as unusual as his ministry makes it out to be.
Lavrov recently had to cancel a trip to Serbia because European airspace was blocked.
He's now on Western sanctions lists.
There can also be no talk of "irreparable damage" for the OSCE because the Russian government is taking part in the conference in Lodz, represented by its ambassador.
The greatest damage may have been done to Lavrov's ego.
Get under the wheels
The OSCE is badly hit for another reason.
The security and cooperation that it is supposed to promote in Europe was finally lost with the Russian attack on Ukraine.
In previous years, the organization, which played an important role in ending the Cold War, had been increasingly crushed by tensions between Russia and the West.
This is unfortunate, because their agreements on conventional arms control should actually prevent new armed conflicts in Europe.
For the "rules-based" German foreign policy, this is another case from which it can learn something about the reality of international relations: the most beautiful treaty is worth nothing if all the states involved do not want to comply with it.
