Embarrassingly, not catastrophically. US proved they will do everything in their power to not risk even the slightest provocation of weak russia (because nukes). Even the prepared response to russia nuking Ukraine was supposed to be sinking of Black Sea Fleet - something Ukrainians managed on their own in ~70% by now despite not having operational navy of their own. Do you really think there will be US response to full on Chinese invasion? I can already predict strongly worded letters and condemnation. US doesnt even have nor want to have a base there.
