Yes, Russia is prodding internal dynamics to their advantage ... internal dynamics that are generally operating against liberal democratic values, and broad international alignment that stymies Russian interests. It is an entirely rational and understandable approach, but lets call a spade a spade. They aren't meeting with these people, giving them indirect support through hacks, etc. in goodwill towards the liberal democratic international order of the West. Case in point. Trump is irrelevant to Russian interests, but a chaotic and dysfunctional political situation in the US is very much in its interests. So, you put out crap about Jill Stein to hurt Clinton.
Russia is operating very much like a 19th c. practitioner of real politik. That in itself is instructive ... there's a reason the international community moved away from a system built upon bilateral deals. It ended in fucking disaster.
Is it in liberal and democratic values to disregard international law to bomb sovereign states, overthrow unfriendly regimes or use economic sanctions against non aligned states, ever expend military presence around the globe? If yes, then maybe you have a point.
