Exactly. Russia has been doing it for decades and it would be foolish to assume China didn't learn from them. Thomas Rid's "Active Measures" covers this in detail, and it's somewhat maddening to read, because it details how much of the civil strife we've experienced that was exacerbated by their actions.

How is "Anyone who disagrees with me is a Russian troll" working out for you liberals?
Blaming Russia (and China) in most cases is a cheap cop out to try to deflect, hide and minimize the actual grievances of people living in USA.
Yes, there's propaganda and most of it doesn't reach the Americans. It's downright insulting to claim their hurts are something that countries on the other side of the world invented.
