Russians, as every half-decent negotiator would do, entered the arena and took a maximalist position.The Russians didn't enter this talks thinking it will work no not at all they are experienced enough to know this
The US then also responded with its own maximalist position.
It is given that both sides will make concessions. The whole point of having the meeting is to determine who will make the most concessions.
Russia knows that the US would never accept its full demands. The US also knows that Russia would also never accept its full counter-demands.
IMO there will be a deal and the concessions done by either side will be masked behind face-saving spin and media propaganda.
