That is a bold assertion to make considering China literally did retaliate against the US in North Korea once already, to the tune of war. Kidnapping heads of states is an act of war. Venezuela can't defend itself, but China certainly will do whatever is necessary to secure its vassal if the alternative is NK collapsing and having US military bases on its border.

You also rule out the possibility of an invasion of Seoul, as though it would be "unfair" -- when you're advocating for and actively in the process of tearing whatever remains of the concept of international law to shreds, what makes you think PRC would be inclined to play nice?

Other than by launching nukes (and getting 10x on themselves) China has no capability to attack the US. I don't think attacking SK is unlikely because it's "unfair", but rather because there's no incentive to do so. The concept of "if you attack Cuba we'll attack Europe" is an old playbook for the commies, and I think was always a bluff.

My point is that since in this scenario SK would likely be involved in some capacity (granting safe passage, harboring US planes, etc) they would suffer retaliation by NK and possibly China.

I don't see what's unlikely about this, it's basically NK's defense strategy.
