I agree the US military still has a lot of significant advantages and that Taiwan would be difficult to take. I disagree that oil would be a major factor because China would just pipe it in from Russia.
That link seems to be about sea routes. I’m talking about a pipeline or most likely multiple pipelines that would be skirting around Mongolia. You’d have to do either a lot of dogfighting to get there if you’re using planes or hope you can get a missile or drone through. A HALO jump sabotage mission would also be super difficult.
