I'll start with the last question.
Yes, the Russians are reaching out to both the far right and the far left in most western societies. I think their ideological preference is for the far right, but they're very instrumental in how they do this, and they also reach out to far-left groups. The idea is to destabilize societies, not necessarily to have most people in a society agree with Russia's ideological view of how the world works.
The Cold War was analogous to this. The Soviet Union did the same thing. Yes, most of its contacts were with the far left in western societies, but it also reached out to and funded far-right groups. The idea, again, is to destabilize and to cause people in the west to give up on the idea of objective truth. The objective there is to cause paralysis. If you give up on the idea of objective truth, you don't know who's right or who's wrong, and then you're paralyzed and you can't react to what the Russians are doing. I think that's the objective.
