Just briefly, I think Russia is open to diplomatic solutions. Russia is prepared to implement the Minsk agreement, but it needs to be implemented by both parties. I think Russia is prepared to imagine a United Nations role. Of course there is disagreement about where United Nations peacekeepers might be based, but those could be worked out.
With respect to the United Nations force, we should be promoting that, but we should not imagine we're in a position to lead it, because by key parties, including Russians and the rebels in the Donbass, we are not regarded as non-partisan. We just aren't. I don't think we would be acceptable leaders in that group. We might be able to participate in it, and we should promote it, but I don't think the notion that we will lead a UN peacekeeping mission in the Donbass is realistic.
