However, if that's what it takes to effect a positive change in regime in China after what the CCP have done in the last year and a half or so to the entire world, one would cheer it on. Indeed, the biological attack against the entire world is testimony to the fact that they, the CCP, love to take casualties because they consider any conflict of attrition to be their strong hand.
Such a comparatively restrained event would still be quite a bit short of strategically nuking the entire place off of the face of the planet and making it forever inhabitable, so there is that.
You are disgusting by wishing the deaths of hundreds of millions of innocent people for your political views - it, if you could carry it out, would make you the largest mass murderer in history.
Such an attack would trigger a nuclear war and the US would be the biggest loser. If we kill 400 million of their people by blowing the 3 Gorges Dam, they would retaliate out of revenge and to save face by doing their utmost to inflict the same number of US casualties.
Additionally, they have a mutual defense treaty with Russia, which would be obliged to come in on the Chinese side - say what you will about Chinese nuclear capabilities, but the Russian capabilities are on par or better than ours, so you would be signing the death warrant for you and yours as well as millions of other innocent US citizens. But you would smugly feel proud of teaching those Chinese a lesson, I suppose.
No the CCP does not “love to take casualties because they consider any conflict of attrition to be their strong hand”. The CCP would take casualties ONLY because they consider their people expendable as long as the power of the CCP is not infringed nor caused to lose face - no matter how slight. And that applies more to Chinese daily life than to any war:
“The CCP wants to control everything and only allows pro-CCP organizations, even in foreign countries. If an organization is big enough, the CCP will try to control it; if it won’t cooperate, the CCP will treat it as an enemy.” - mainland Chinese overseas student.
Every one of those casualties would be a family’s only child. They can’t keep that up for long.
