We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
I doubt it. We are nowhere as strong militarily as we pretend to be. I question whether we could win a war with China at this point. Plus with a divided Washington and a political opposition determined to undermine the present administration by any means possible, you will not get political support for defending Taiwan. I also doubt Americans would support loss of American lives defending a country most know little about and have no emotional ties to (one of the effects of Chinese propaganda effectively isolating Taiwan for so many years), even if in fact Taiwan is one of the leading countries in Asia and a model for the success of western-based democracy.
Japan is more likely to want to defend Taiwan because of long cultural and economic ties between the countries. (Taiwan was part of Japan until the end of WWII and Japan still heavily influences Taiwan.) But Japan does not have the capability to fight China.
It's too bad. Taiwan is a very nice place, basically a civilized version of China with a melding of Chinese and Japanese cultures which makes it quite interesting. (Unfortunately, it's also very hot most of the year and has a lot of earthquakes and typhoons.)
The only thing stopping China is negative world opinion, especially if it involves violence and loss of life.
