The question will have the answer in a year or two, the reality is that the agenda of the US-Russian relation it is not an easy one and each issue took apart needs a special approach. Hence, probably, the occasion for the Russian counterpart to feel confused or not very happy when they are not hearing what they would like to. It is a matter of managing international affairs at the global level. No opportunities to complain or to feel unhappy. It is not a love affair, but a competition between big powers. The rest is PR, of course. And understanding the "bad cop"/"good cop" rules.
