All these could be valid grievances. Great powers keep poking and prodding each other all the time. Russia does all sorts of chicanery back. They are mounting right not psy ops in Eastern Europe (e.g. the current "word" over there is that they are in danger of being nuked because of the US bases, and it's all US's fault, they'd be just fine if US got out of there... and some people swallow that stuff hook, line and sinker).

Russia and the US spy each other. The US sanctioned Russia because of the Manitsky assassination. One can easily claim that this is economic warfare, and the if it weren't for that assassination, some other pretext could have been found. On the other hand Russia does kill people (and in the process they increase the popular awareness to such technical tems as Polonium and Novichok).

This is again, just to say Russia and the US keep taking shots of each other. That does not mean Russia needs to start a real war, where tens of thousands of people die. And if Russia does, that's in no way the US's fault.
