The Donbass separatists are unhappy with Putin. One of their most notorious leaders, Oleg Tsaryov, made a statement saying (translation is mine), “We don’t need tanks and drones, we need soldiers who will defend peaceful citizens from Kiev aggressors. We need the might of the entire Russian army. . . If all we keep getting are tanks are puny financial resources, we will not be able to defend these cities from fascist forces.”
The problem the separatists are facing is that, even though there are quite a few people in the region who kind of wouldn’t mind becoming part of Russia, none of them are willing to go to actual battle and die for the cause. Even separatist bandits are recognizing that they are trying to give the people of Donbass what these people don’t really want a whole lot.
