The US military should be ready for all possibilities. However, I expect Taiwan to be peacefully handed over to the Chinese, just like Hong Kong was. We heard similar rumblings over it before they were merged.
“One China” is the official policy of all the major governments involved, with regard to Taiwan. An invasion by China won’t be necessary unless the Taiwanese start backing out of their agreements, which they are not so far doing, that I’m aware of.
The chip manufacturing capabilities there are much too fragile to sustain any sort of war damage whatsoever, and survive, and the whole world would suffer immense manufacturing issues of all tech products were that to happen. Therefore, I don’t expect it to happen.
The chip manufacturing essentials are in the heads of the engineers and management of TSMC.
Loss of manufacturing facilities is always temporary, if the people survive.
The Demonrats get most of their ideas from communists, and vice-versa. Because Taiwan's and China's economies are so integrated, 40% of Taiwan's mostly socialist voters are already willing to merge with communist China. China could get that to 51% with a little Demonrat-style immigration/voter replacement. And the immigrants wouldn't even need to assimilate a new language.
Roughly 30% of the Taiwan population is Pro China and at least superficially in favor of reunification.
Hard to believe,but true.
