Let me rephrase this: If China takes over Taiwan, how soon can USA build a united force with Japan, Australia, South Korea, probably British, India etc to take it back, like what occurred in Kuwart? This might set all of us back 2 decades but other options will be worse?

China has nukes. So do the United States, Britain, and India.

None of the leaders of the listed nations want to die in a nuclear holocaust.

So no, your "united force" will never happen.

Some of these responses are really silly. What actually happens is: - TSMC's foundries stop operating soon because they're not getting new equipment, replacement parts, or supplies to operate the foundry from ASML or anyone else in the West, thanks to the inevitable embargo/sanctions that would follow. Even if the fabs were supplied and operating, nobody would dare send their designs to them to be fabbed anyway. - TS…

>extremely tight for several years then life goes on

Strange way of saying "$2 Trillion Apple goes bankrupt because no chips means no product to sell".

Pretty sure Apple would still be there.

Remember, it is not just Apple that would be hit. All their competition would also. And out of all companies that produce phones Apple has probably most cash on hand. They have something like 200B USD in cash.

Also Apple is in best position to be first in line to by chips at a premium outside Taiwan as their products are already expensive and high margin. And even if that doesn't work, they are in best position to just set up their own production. This would take couple of years but would set them to kill all their competition for foreseeable future so I am pretty sure they would look it as fabulous investment.

Look at latest iPhone teardowns. There is just couple of chips in it, and already designed by Apple.

The only other company I can think of is Samsung, that sits on a pile of cash half the size of Apple's. But while Samsung is well diversified, basically all their lines of business rely on chips, too. While Apple does not need a lot of different types of chips, Samsung probably relies on so many that they would not be able to replicate all of them.

No matter what happens to the fabs, China wins either way because they manufacture everything. As the recent crisis showed when push comes to shove China takes care of their internal needs first.

> As the recent crisis showed when push comes to shove China takes care of their internal needs first. Not sure what you mean by "internal needs", but China is currently suffering mass blackout because China banned Australian coal. Seems to me that China puts its domestic politics in front of people's need. * Well, at least not burning coal is a massive win for the Earth, so there's that. :/

They are probably referring to medical gear at the early stages of COVID. China wouldn't export things they thought they would need even if there were contracts for items.

They also took it a step further and asked Chinese in other countries to get medical supplies back to China potentially leaving other countries in difficulty. E.g. https://www.smh.com.au/national/second-developer-flies-82-to...

It should be a wake up call for politicians, though no doubt will be forgotten. International trade is great and but this clearly showed nations should keep some base activity domestically for key/essential industries.

Chinese takeover of Taiwan would mean war or trade war, in both cases all sides lose, China loses worse.

A lot of countries are building up reasons to not like China, that would be the tipping point.

Manufacturing would flood out of the country, there'd be massive sanctions, other fabs would ramp up and more would be set up over time.

'Belt And Road' would be kaput, and a bunch of nations that supposedly owe China money would probably cancel their debt.

It would cause a recession and everything would slow down for a bit, but that would be the tipping point for the 'Next Phase' of China's development and it would be bad news.

There would be war over it.

Line in Ukraine with extensive defense warranties? https://en.wikipedia.org/wiki/Budapest_Memorandum_on_Securit...

Crimea has no value to anyone, it's a sparsely populated barely industrialized island and 1/2 the population is Russian anyhow.

I don't think there will be war over Taiwan, because if it was an effective Chinese invasion - there is nothing anyone could do about it. If China takes the Island, then they will keep it, not even the US could displace them without incredible force of power.

If the US was involved in the fight and US took casualties i.e. downed fighters/bombers, or worse, a ship sunk, then the US will extract blood for that in other ways, notably, I can see the US and allies pushing China out out of the S. China Sea as a form of retaliation because it's militarily plausible.

But it would take nuclear war for anyone to push China off of Taiwan if they secured it and were well dug in and nobody's going to do that.

wonder if there's a plan to evac everyone who has crucial know-how abroad, a la Operation Paperclip and its soviet counterpart. If they can move all of the machinery and people out in time( This is taking into account, that the worst has come to happen ). They could setup shop elsewhere in probably under a year.

I've somewhat joked on other forums that this is exactly what the US should do. Wholesale shift the entire population and industry of Taiwan to Texas/Arizona/New Mexico/Colorado. Green cards for everyone. Like when the Soviets shifted their heavy industry to the Urals during Operation Barbarossa. The Chinese military would walk into Taipei and only find a note with "you wanted this rock...you can have it middle finger" as a tumbleweed rolls by...

TSMC like most advanced fabs rely on western supply chains for operation. TW fabs aren't priority targets for PRC take over, they're useful barginning chips for PRC more than TW. PRC will offer US some sort of production continuity and US will pressure TW gov to accept. Losing TSMC will set back US/western high tech industry years.

But ultimately TSMC is expendable. TSMC is a media side show that obfuscates the actual amount of strategic semi assets PRC can physically threaten that will take decades to diversify out of trivial PRC striking range. Most of which are in Korea/Japan with US security guarantee, hence TW getting more reporting - it's under more theoretic "threat", combined with TMSC making all the leading edge chips for newsworthy products.

East Asian supply chain supports ~80% of global semiconductor production. Destroying TW fabs sets back a few generations of leading edge nodes which are already deniable to PRC due to US origin tech% and effects some high tech industries. PRC undermining/destroying east Asian fabs will set back global semiconductor capex for decades an every node which is essential to every western industry that requires a chip. It will constrain majority of global manufacturing to 90-00s technology. That's the real semi MAD, and why everyone is trying to build capex off TW island.
