It is difficult to say what is expected of the new US plenipotentiary representative for Ukraine, it is obviously a transfer-communicative link in the relations between Washington and Moscow. Previously, this role played Nuland, now it was replaced by Volcker. Nuland and Volker are not sympathizers of the Russian Federation and are, in fact, representatives of those circles who stood for organizing a coup d’état in Ukraine. It is extremely unlikely that the replacement of personalities here will affect something, because the contradictions here are of a strategic and ideological nature.
It is worth remembering that for all the jokes about “cookies Nuland”, it has a respectable share of responsibility for the coup d’etat and unleashed in Ukraine a civil war.
