> HK democracy for example is seen as such a threat to China that it must defacto invade HK to stop democracy from overthrowing the CCP.

Which it has largely done, and moves on. Saying it's not resilient enough to handle the situation seems to be wishful thinking in that case (and is obviously false in the case of Tiananmen Square or Tibet.)

That’s my point. The CCP appears so weak that anything scary must be attacked viciously. Admit no fault. Allow no dissent. If the CCP was stable and strong it wouldn’t need to invade HK. The invasion demonstrates the weakness.

Oh no, it's not a weakness. It's the authoritarian version of a team building exercise.
