The talks in Geneva resulted in an agreement that is in favor of all that is good and opposed to all that is bad. That's the basic gist of it; but what does that mean? Let's translate this memorandum from the language of high diplomacy into the language of the Ukrainian crisis.
Kiev's government representative was invited to participate in his role as a potted plant—because there is nothing to discuss with him. On this all the participants were in complete agreement. That is, there is no government in Kiev, in the sense of an entity that exercises sovereign authority over the territory of Ukraine. This is understood equally well in Moscow, in Brussels and even in Washington. Thus, the actual talks were between USA+EU and Russia.
Russia's position is that Kiev doesn't have a government, it has a God-only-knows-what. It makes no difference what they are called or who they are. They have no power and they control nothing. They do not control the economy, or energy, or the army, or the police, or even their supporters who are running around waving machine guns.
The position of USA+EU: “That's not true! There's a perfectly nice government in Kiev, we made it ourselves, and we hold discussions and even sign agreements with them.”
In view of the difference between these two positions, further discussion is pointless. Therefore, it is necessary to run an experiment and to establish a simple fact: are the dramatis personae in Kiev a government, or aren't they?
The authorities in Kiev have to prove themselves. To do that, they have to disarm and reign in their freaky supporters, grant amnesty to their opponents, and begin to exercise control over the army and the police. If they prove that they are in control, then it will possible to move to the next phase in resolving the crisis.
The ball is now in their court. If they can prove that they are a power, then there will be a step-by-step resolution to the crisis. If they don't, then the crisis will be resolved on their behalf, and they won't be invited to participate, even as potted plants.
Considering that these personages have already reneged on a previous international agreement—in February of this year—it might have been smarter for them not to sign this one. Because if they don't live up to this one either, then nobody will want to offer them political cover—not Brussels, not even Washington.
