Oh, I get it. There’s no questions that our operation in Iran is working to the benefit of China, and perhaps to a lesser extent Russia.

Hahahahahahahahahaha! This funny.

If I were China, high up on my wish list would be, “a situation where the US has vastly fewer missile interceptors to be able to send to Taiwan on a moments’ notice for the next few years.”

WOW. Yeah, no.
The Chinese just got not 1 but 2 front row seats to the US scything through their equipment without breaking a sweat. Then they're watching the US and Israel knock down an extremely high percentage of rockets and drones, both things that also contain Chinese tech.

Your comment on China's "geopolitical position" is also off base: China didn't so much as squeak either time the United States took action. There's a big reason why the rest of the Gulf States are squarely in the US' camp right now: They get who the strong horse is.

Then there's the matter of China's oil supply. Say, are the tankers getting through to them anymore?

And of course let's ask exactly who in China is h appy...since they don't have any military leadership anymore.

Knocking over Venezuela took a bishop off the board. Knocking over Iran takes a rook off the board. When Cuba goes - and it will - there goes another bishop. By systematically eliminating safe energy harbors for China Trump is putting them at a strategic disadvantage...so they think twice about doing anything.
