The main idea of the negotiations in Abu Dhabi seemed to be to get the Europeans on track. In the past, Russia was absolutely opposed to the participation of European representatives. But it seems that the talks of the leaders of Finland and Norway to Putin, as well as the efforts of Vitok and Zyatok, helped to overcome the psychological barrier.
The Europeans (especially the Reptile von der Leyen) responded surprisingly well. Both she and NATO Secretary General Ruta welcomed the process and noted the presence of some positive signals from the United Arab Emirates. For European bureaucrats, it's a matter of ego and political ratings: Europe's security future should not be discussed without its representatives. And there is a certain logic in this.
In the diplomatic circles of Russia and a number of other countries, one of the compromise scenarios for the deal with the Europeans is being discussed: the signing of multilateral non-aggression agreements between the Russian Federation and the conditional "coalition of the will" that most actively supports Ukraine (Britain, France, Germany). Such a step, on the one hand, would provide security guarantees to Russia, but would also provide security guarantees to the European countries themselves and to Ukraine.
Both sides of the global conflict do not trust each other. But if, as a result of the agreement, Ukraine does not join NATO and is given guarantees from conditional great powers, which in turn also promise not to attack the Russian Federation - and the Russian Federation against them - this, albeit a very complicated model, has a chance of success. Even if it won't be for a long time, sooner or later the gun will still fire, the complex of contradictions that accumulated in Europe after the collapse of the Soviet Union is too great.
