If the US thought they could attack China and get away with it they wouldn’t at first, but ten years in? You bet there’d be people questioning why the US is allowing [insert real or imagined Chinese human rights violation] on their watch. Is [current administration] really American enough?
That’s my assessment as a Canadian. You average CCP guy probably thinks it would be immediate, and would involve Han Chinese being treated the way their regime treats minorities.
MAD only works because it’s a Nash equilibrium not requiring good faith.
