Australia, The Philippines, Japan, South Korea, the UK, and possibly France would join American military intervention. Not to mention Taiwan itself. Probably get logistical support from other places like Singapore, Thailand, etc.

American sentiment would change if mass casualties were inflicted on US troops.

This war scenario is different for Americans than Vietnam, Afghanistan, Iraq, etc. There is direct threat to the American homeland if Taiwan falls. Not to mention destroying our technology infrastructure and industry.
