If what you write is true (and I have no reason to doubt it as you seem well-informed), this would be a very effective deterrent to war altogether. China is probably flexing her muscles for the same reason most revolutionary regimes flex their muscles- to paper over internal problems and divisions by focusing on a foreign adversary.
All Taiwan needs is assistance with Satellite intelligence and also with the Navy guarding the West coast and to keep supply lines open to Taiwan. If the US does those three things Taiwan can do the rest. Also the Philippines, Japan, S. Korea and Australia should see this as being critical for their own survival. They can help with their navies, with soldiers, and with supplies. You don't have to be on the front lines to be very helpful.
Not only so but I suspect India would not want China to win that war anymore than Russia wanted us to get peace in Afghanistan.
