If DPR and LPR invite Russian forces and the Russian Federation agrees, that's an action done on the bases of this consent. Alright. Thanks for clarifying.
Coercion? What Ukraine does right now, thinking about stopping the gas as one of their "sanctions" (I wonder who told them to do that, Europeans certainly didn't) is nothing but coercion. Europeans talk with them about the reverse flow and they do "our friends behind the pond told us to stop the gas, so we can use it as a leverage against Europeans, so they help us end this war fast or they're without gas", they can go fuck themselves.
