What are your thoughts on that? Do you think USA and the allies will help Taiwan in case a war would break out? Or rather Taiwan will sadly succumb into the PRC regime against people's will?
Please do not comment if you hold the position in favor of PRC and consider Taiwan a Chinese province. I don't need this type of morons on this thread.
You don't really get to request such a thing. People could make the case in favour of it being a rebellious province, as per the PRC position, though for pragmatic purposes most would disagree (it has its own government, passports, technically embassies...)
Still I figure the US would probably wimp out. They would send a strongly worded letter, maybe even a do nothing sanction, but even if they were not going through another isolationist phase (and they seem to be, regardless of political party) the ability for them to take on China is limited and would likely only do it to save themselves rather than playing world police.
Europe is not really in a position to do force projection there (the economics are not good, and that is without taking in a good chunk of the middle east and north Africa's not quite finest, and China pulling more than a few key strings there), and the UK is not much better (might do something for Hong Kong, even if that is just offer passports to those that might qualify). China and Africa are already thralls of China, no chance the middle east will do anything, Australia could maybe just about defend itself (and would likely suffer massively on the economic front as China is a fairly big part of its economy), Russia has its own issues (its birth rate/population collapse is only marginally better than China) and is probably playing the long game anyway (though might take a bit of land if it can), India would only intervene if it is was in its own interest or could catch China on the back foot.
Others above debate whether it would be in the economic interests of people to go against China here, and that is always the main reason for anything. If China is the world's factory (at least for another decade or so before wages shoot up more there) then Taiwan is the good factory (good materials, actual tolerances... make stuff that is nice to use) where China tends to make junk. That means something but I imagine places are going for more of a strategic reserve approach here, if not national security, and rolling their own factories despite the costs or leaning into robots to reduce costs as much as is possible.
This guy covers what would go there if the US tried it on.
China's military efficacy is debated (most think it would not do well) but getting marginally better. The US... not so much, though enough to still make a dent in places.
With neutral US
China is also on the verge of some pretty unpleasant fates
Plus a couple more on water and internal stability (there is a reason they are ramping up the surveillance, fabricating nationalism and the like, though even before you consider that then for all China's authoritarian tendencies their internal provinces have a lot of sway).
When unstable countries need a focusing point then they tend to create a war* to try to pull focus from the failures of governance. If they win then they get a little reprieve while people are riding high from that, if they fail then they collapse faster.
*can pick things from ancient times to today if you want. Rome had its fair share, Argentina-Falklands was probably one of these, south America in general is full of them, Africa can be these but more often is lines on a map being drawn by people that never set foot there and did not understand anything there, USSR-Afghanistan, Finland-Russia this though also need of a better port, possibly World War 2, whether Japanese imperialism in the early-mid 1900s was this is harder to say but it did not hurt, Napoleon's various efforts are at some level this, Italy in more modern times is this (the farce that was Italian colonialism through world war 2 for instance), the middle east has this every 5 minutes it seems...
For my money the fate of Hong Kong will probably be the thing to watch there. That is going to get flattened before too long, when that goes then they will probably coast off that for a while and then contemplate Taiwan, unless a suitable African target of belt and road becomes a thing, or maybe they can swipe something from India (probably by starting something with the Sri Lanka set or Pakistan set, that or doing the usual fund and arm and independence movement somewhere and you have endless choices here), maybe go enforce a debt collection from some state they have given a loan to that is now not agreeing to pay it or hand over one of their shiny ports/mines/oil refineries or something.
Short version. You better hope China's coming collapse is short, sharp and swift so they can't do a war of diversion on Taiwan. Also better hope nobody finds oil or something valuable in all those disputed islands/surrounding waters as that will be more than an issue with coastal defences/exclusion zones is nice.
You also better hope China's influence policies don't suddenly actually get good (see also Russia, U.K., US... spies, political and economic influencing and whatnot) rather than pretty laughable like it is at present (and they even have the benefit here of speaking nominally the same language compared to far different efforts like English where nuance is crazy hard). From what I have seen of political things in Taiwan this last few years then mainland China's sock puppets in political parties there are increasing in monetary support despite no real grass roots support such that they could be a real threat there, even more so if they decide to mess with the fairness of elections. If said sock puppets get enough power that they can open the borders (and presumably dump a load of money to make it worth it)... oh dear.
