A grim look at Taiwan's ability to repel a Chinese invasion; with critical commentary by 2 ex Taiwanese senior officials and a ex conscript who never touched a gun in 11 months of training.
Certainly from what I've heard and seen it would be a big ask, Taiwan conscription is widely known to not be very effective, much of Taiwans equipment is older un-upgraded gear, and some of the locally designed and made stuff never got enough funding and support to really bring it up to code. Equipment and munitions are generally in short supply, particularly on delivered and ready to go on Taiwan itself.
Meanwhile China is clearly doubling down and going from strength to strength. Internally they see themselves as very strong, much stronger than Taiwan, but also now able to eclipse US and allied power particularly when so close to Chinese territory. Also their political power is seen as simply unmatched. China assimilated Hong Kong and implemented what they wanted, and realistically, no one said boo. Some people left, some people protested, but China was easily able to handle that. So they see that as a total win. They see it as proven capability, and an ongoing success.
Ukraine is much larger in population and area than Taiwan, and China is much, much, much stronger economically and military than Russia and orders of magnitude stronger than Taiwan. Unlike Ukraine which is right on the border of NATO and a clear sovereign country. Taiwan is very much alone, and everyone, some in Taiwan, while 100% of China, the US, the UN pretty much agree with one China policy and only recognize China, even if the US has made assurances it will defend Taiwan from attack.
If China launches a massive rocket attack, against all military targets in Taiwan, its not clear to me, how the US will stop that. If there is zero military capability in Taiwan, its 100km away, I'm not sure by the time anyone else gets there what there will be left to attack/defend and if any nearby US forces would be enough to do it. Particularly if the Chinese put forward the idea that they would launch attacks on US forces on Guam, Japan and SK if the US tried.
The US China balance isn't the same as in the 1950's or 1960's or the 1970s when Nixon visited.
