I think there's too many variables there to make a solid guess.
They certainly
want to, but I don't think they are willing to risk a shooting war with NATO over it. I don't know enough about Aussie politics to guess where they stand on Taiwan, but a couple nuclear attack boats are a pretty pointed message to a country with 1.5 working carrier.
The west, on the other hand, could use a good shooting war to unify the disparate tribes we are dealing with.
Additionally, as we have said in other threads, China is running into resource problems in expanding their coprosperity sphere, which I think is more of a driver to their actions than Taiwan.
And lastly, if I were Taiwan, I would be making it known to all of the west that all the advanced chip plants they have are rigged to blow, and if China comes in and they don't get help they are taking
92% of the worlds advanced microchips with them.
Throw in some cultural communication issues between east and west, any upheaval in China internally, and the US's .......let's say tumultuous political environment, and you might as well be throwing chicken bones.
