Also USA presidential elections are joke, and definitely not a good benchmark to look at. Whole world somehow understands that simple vote by every single citizen is the best way to elect a leader, if you prefer democratic process in general. Also USA is definitely not even close to the ruzzia. I wouldn't evaluate China here, but ruzzia and USA are pretty much on the opposite spectrum in mentality, until Orange-man at least.
As for Russian and American mentality - there many similarities, from glorifying their army, to feeling that they have god-given right to invade anyone, shielding war criminals, being skewed towards religious fundamentalism, to assuming there’s nothing good coming from the government… to a surprisingly short history of their country.
Again, China is not Russia. Mentality-wise, USA is closer to Russia than China is.
