Russia will definitly get what it wants.
The US has been testing the waters on many fronts, it's a smart to thing to do, albeit risky. They can afford to trade off a few of their holdings if it means they can get what they want in other regions.
That's always been in the US' favor: having their hands all over the place so they can make concessions when they need something.
I don't see Russia stopping the US on other fronts such as in the ME. And like I said before, Iran is toasted, they can do nothing to defend themselves if an attack was ever carried out against specific infrastructure/facilities that can be linked to the production of nuclear weapons. They would have no justifiable targets to reply against, and they could not attack anything that is linked to the world economy such as oil production facilities.
Russia, China, and the US are all just moving their pieces without any intention to confront one another because they can always make trade offs. But in this game you have to pretend you are not interested in making concessions to begin with so that no one profits from the situation significantly moreso than expected, and you need to have something to trade in order to get what you want.
