Yes. Exactly.
The other problem is credibility. China claims Taiwan as its territory but has zero control over that territory. Chinese president can't visit it. Other nations' politicians are visiting it, walking over all the promises they made in the past. That is not a good look for a country which is supposed to become a geopolitical pole, you know. I'd have serious concerns about China's power and its will to use it if I was a 3rd country. This superpower has a province under separatist control.
Then there is the de-sinicization. A very good chunk of the Taiwanese youth doesn't identify as Chinese at any level. Ask Chinese-origin people in Malaysia, Singapore, the US and Europe and they will say they are ethnically Chinese. Taiwanese youth don't identify as even ethnic Chinese.
I also believe the balance of power will stop changing fast around 2028 or so. The US is switching to an asymmetric doctrine. Militarized islands, austere bases, SAMs, SSMs, AShMs on trucks, etc... Japan and Taiwan will modernize from a low base etc. I don't think there is any point in waiting after that.
The biggest problem is that Taiwan is China's diplomatic and strategic black hole which saps all of its energy
Imagine if China didn't have the problem with dealing with Taiwan, how much more freely it could operate in the international arena. It spends tremendous diplomatic capital every year when dealing with the Taiwan problem, imagine all that diplomatic capital invested somewhere else
This is also why the US is interested in using Taiwan to distract China from seriously challenging it in other areas
I still can't tell if Taiwan is China's "red line" or a GIGANTIC red herring. Like, with the way they parade around the "One China" policy everywhere, or very deliberately tell the US (which we all know has the impulse control of a toddler) "don't do this, this, and this, here, I've even made a bullet pointed list things I don't want you to do and
exactly how to do them". Then they let small states like Lithuania troll them, and make a big deal to win over inconsequential Latin American nations on Taiwan. "Look, here's my weak spot. Guys, this is my weak spot, if you want to hurt me, hit right here".
I understand there are merits to keeping Taiwan from international political recognition, but the actual security threats a small island presents are very low to the world's largest navy. However, it
is perfect bait for the US, for whom proxy war is their modus operandi. It's almost as if this whole scenario was hand-crafted for them. "Keep your tunnel vision on Taiwan and Taiwanese semiconductors
, definitely don't mind the alliances we're building in Eurasia+Oceania or our quantum leaps". In this sense, I'd say the Taiwan issue does give China diplomatic freedom, as well as control over escalation methods and ladder.
I also don't believe that PRC needs immediate reunification for internal purposes (projection from the West again). China isn't like the US, their people are not the hawkish warmongering type, and they have faith in their government to execute long-term plans. PRC could just say "we'll handle the reunification issue when we are good and ready, don't worry", and I feel like people wouldn't mind. 5, 10, 20 years, they are the blink of an eye in Chinese history. The public will be happy as long as economic growth continues and common prosperity is realized.
