I still have a fools hope that generals and other high ranking military people have their feet firmly on the ground, as their whole training, career and often identity necessities. And, at least on my belief, that also means that they won’t lead their military across the ocean to get their ass handed over.

I’m quite confident that US military could defeat their Chinese counterpart on a level field, but fighting across the ocean is a logistical nightmare and even if they could get their boots on the ground against Chinese holding anything there would be nearly impossible and it would have an astronomical price tag. USA might be able to pull that off, but in the long term it would just be another Vietnam, but with far more severe consequences locally.

So, yes, I assume that generals would disobey. And any competent replacement would disobey too. Replacing them with someone who don’t know what they’re doing would just be a disaster for the US of A. It might still happen, but at that point they’d look like the “second strongest army in the world” which is being destroyed on a field in Ukraine and there would be no hope for anyone in the Europe (or maybe globally) who would like to do any meaningful business with the US, so they’d just dig their own grave. pretty much like what Russia is doing right now.
