back to article US Army journal's top paper from 2021 says Taiwan should destroy TSMC if China invades

A top US Army War College paper suggests Taiwan should credibly threaten to eradicate its semiconductor industry if threatened by China so that Beijing would no longer be interested in unification. The US Army War College showed the paper was its most popular of the year, when it revealed it topped a list of the most …

    I'm not convinced. China's need to re-absorb Taiwan is deeply idealogical rather than motivated by economic considerations. I expect a Punic Wars solution with all of Taiwan salted and unliveable would be acceptable to Beijing, and certainly dear old Not Omicron or Nu.

    What does that say about US warfighters' insight.

      There is no "re-absorption" involved as Taiwan has never been under control of the PRC. In fact Taiwan's links with China are tenuous at best with barely 200 of dynastic Chinese governance in Taiwan's tens of thousands of years of human settlement.

      I'm actually very happy to see the original article was edited from "re-unified" to "unified" - a small but important point as "re-unified" is a loaded term and the actual direct translation from the term "tong yi" used by China is simply "unification".

        There is no way that any sensible person would ever think that the "Republic of China" (Taiwan) was in any way connected to the "People's Republic of China" (China). One of them by it's very name tells you that it is full of communist!

        The current majority in Taiwan has nothing to do with the original settlers though.

        The island was basically invaded by mainlanders in 1949, the defeated ROCarmy established its own dictatorship and pushed natives out of the way in a very ungentle way, then worked hard at assimilating them, whether they wanted it or not.

          Some very unpleasant things certainly went on. However, it is not clear to me that whatever reparations the original local/native population of Taiwan might deserve, that that process would be helped in any way by a PRC invasion, followed by government by communist dictatorship.

          Rewriting history is, of course, the prerogative of the winner.

          The "ROCarmy" was acknowledged as the rightful government of the whole of China only while it remained convenient to the rest of us. The dispute over who should govern the whole of China - not just mainland - still divides the island's politics. That's sort of acknowledged in your post yet you hide it.

          The Han had lived in Formosa for many years before that and the Han had come to dominate the culture, under various other control; the Portuguese (who give the island its name), the Dutch, the Japanese (who were ousted after a military settlement that assigned ownership of the island to China).

          Yes, the Han are extremely racist, but nothing on a scale with we Christians. The course of racial discrimination in the east seems, to me, to mirror that of the same behavior in my own, carefully circumscribed, country the US, yet the excesses are not worse; that would be difficult to achieve.

            I'm not sure that many people living in western countries (including overseas Chinese) understand just how racist China as a whole really is. The idea of Chinese (Han) blood being intertwined with China as a country and the CCP is written into law. For example you could be a third generation descendant of Chinese great grandparents with no PRC nationality and only a UK passport but you will be treated differently under certain laws compared with a foreign visitor of non Han ethnicity. Could you imagine the UK or US saying in 2022 that white people get reduced school fees or anglo saxons have a special route to citizenship? To be fair this is also the case in Taiwan but the laws are slowly changing here.

        unification = invasion

        Let's just call it what it IS: "Invasion" (not "unification")

        [When Germany did this to France in 1940 we called it what it was.]

        Using "their term" is a bit like Chamberlain's appeasement policy isn't it?

        This sounds to me like offshore production needs to move back ON shore, ASAP.

          If mainland china really wanted unification, there is one way they could possibly achieve it with no bloodshed.

          The current communist party mainland government just has to dissolve itself and invite the Taiwan government to take over administration of the mainland. Assuming the Taiwanese government is interested, unification is achieved peacefully.

          Probably not what the CCP really has in mind though when they talk about unification.

          Re: unification = invasion

          I think we can all see what even the most "peaceful" takeover of Taiwan would look like by looking at Hong Kong. The PCR would sign a treaty, then start violating it and engaging in mafia-like behavior.

          China, like many other authoritarian regimes such as Russia, use Rule by Law to subjugate their people. Ruly by Law is where laws are passed that are so vaguely worded that in conjunction with a subjugated judiciary, can be used as a weapon against any citizen for any reason if they displease the regime. Anyone who questions the regime is hit with charges against laws so vague & presumption of guilt is the default so that innocence impossible.* This is the exact opposite of Rule of Law where the arbitrary exercise of power is subordinated to well-defined and established laws interpreted by an independent judiciary.

          The West should simply decimate all foundries in Taiwan the second the PRC acts militarily against Taiwan no matter how small the act.

        Some people are simply ignorant of history.

        China could care less about Taiwan for centuries until China had a civil war where the leader of the losing side escaped to Taiwan and set up his own version of China there eventually named the Republic of China. The CCP goes apoplectic at the mention of the Republic of China (hence why the name Taiwan is used) and threatens world nuclear holocaust any time it is brought up.

        The CPC wants Taiwan as a prize. It can be a barren uninhabited island covered in craters of radioactive glass and they'd be happy.

        Taiwan is a beacon of democratic resistance to the communist dictatorship. That alone is enough to damn them. Hong Kong, Tibet, the Urghars, the South China Sea (and many others), all ground under the heel of a despot nation to prove their superiority.

        Every nation on Earth should recognize Taiwan as an independent country and place Red China under the heaviest of sanctions until the CPC amend their ways for the better.

        Typing those words in China would subject me to a three year jail sentence.

      As of 2025, it would mean that China would hold most of the cards, if Taiwan destroyed its fabs.

      The West would still need chips and the build-up of capacity in China would leave them sitting pretty to pick up the pieces, even if their tech was artificially restricted due to trade embargoes before the action. Larger processes are better than no processes.

      And the engineers? Unless they go up in smoke, along with the factories, expect them to be forced to work for Chinese foundaries.

      Also, an automated system to destroy the factories? What could possibly go wrong?

      I think the whole paper is very short sighted and ignored many obvious facts, especially that this has nothing to do with technology, directly.

      1. Triggerfish

        It strikes me they destroy all their chip manufacturing and they lose the reason countries may be interested in defending them.

      Nobody (other than readers here) has ever suggest that the motive for unification is economic.

      Even the article you are responding to doesn't make that claim about the paper: The Register reports and the paper take the position that, lacking a burnt-earth policy, an invasion would be economically neutral: that chip factories would continue to supply China as they do now.

      The suggestion, which is credible, is that economic penalties might discourage invasion.

          Probably removing foreign airbases from their shore comes first, followed by having control over the seas between Japan/Korea and the Phillipines. Preventing their citizens getting the idea that China could live without the communist party comes third. Economics come last and they might be prepared to ride out 20 years of sanctions from the rest of the world.

        You can't truly understand how irrational China can and will be about the "face" aspect of Taiwan until you have had an argument with a Chinese neighbor or driver.

        If Xi thought he could mostly get away with it and avoid causing too much damage to the Chinese mainland he would quite happily nuke the whole island and a large percentage of the PRC masses would cheer him on. There is a phrase commonly passed around message boards in China that loosely translates to "keep the island, not the people". As far Chinese are concerned Taiwan is Unfinished Business with the Japanese and to some degree America/the West in general.

      "China's need to re-absorb Taiwan is deeply idealogical rather than motivated by economic considerations. "

      I doubt that. All previous land grabs in human history have been over money and power. Why would this one be different?

      1. ShortLegs

        The PRCs 'desire' to grab Taiwan goes back before Taiwan became an economic success, way before TMSC.

        The Chinese view it very differently to us. For them, it is not invasion or [re-] unification, it is pulling an upstat province that illegally left the PRC back into the fold.

          Taiwan was never part of the PRC. It has never been governed by the CCP. It may have been part of China when the Kuomintang was in power. Then they simply moved there and continued to govern after losing the mainland to the CCP. So if anything, the mainland is the breakaway territory that usurped the then government.

      2. llaryllama

        I'm Taiwanese and the above quote is 110% correct. China would absolutely nuke Taiwan and leave it an empty radioactive wasteland if they were completely sure it wouldn't backfire and cause internal unrest. They can't be completely sure and that's the only thing that's stopping them.

    How many of those downloads came from the PRC?

    Just asking.

    I used to write scenarios for brass (military and non). They are a dime a dozen (well, more like $1M per). Should be taken with grains of salt. However sometimes one of these scenarios is latched onto by someone with too much authority and frequently not enough brains and becomes some form of reality.

    US Army plans to destroy world economy.

    "US Army journal's top paper from 2021 says Taiwan should destroy TSMC if China invades"

    And then watch the Western economy tank as the world supply of all the many various vendor's chips TSMC manufacture for them dries up. One only has to watch what's happening at the moment with semiconductor shortages to get a flavour of that. TSMC has a 50% market share of the total world silicon foundry market, heavily biased toward the more crucial high density and low power areas of the market.

      More crucial only for gaming PCs and smartphones - not for military kit or power parts.

      The current semiconductor shortage that is crippling industry isn't a shortage of 3090 graphics cards or other 5nm parts

      1. Ian Mason

        Re: US Army plans to destroy world economy.

        No it’s not, and if you think that a company that represents 50% of the world’s fab capacity is just turning out “3090 graphics cards or other 5nm parts” then you’ve got a rather poor grasp of what the semiconductor industry produces.

      2. Boothy Silver badge

        Re: US Army plans to destroy world economy.

        5nm parts currently account for about 14% of TSMCs revenue, and as this is a fairly new node. these will likely still be higher margin parts, so actual % of production will likely be quite a bit less.

        7nm is around 35% of revenue (the largest single node by revenue). All other revenue (51%) is from 16nm through to 90nm+. TSMC make a lot of chips other than high end CPUs, high voltage, high thermal, hardened, radio silicon etc. Also the 16nm and bigger is likely to be low margin bulk items, so to get that 51% revenue, this likely accounts for a much larger % of the silicon produced compared to 7nm and 5nm.

        Also just for ref, Nvidia 3000 series cards use 8nm chip from Samsung, nothing to do with TSMC.

      Perhaps this indicates a problem with too many eggs in one basket and shows that the world needs more diverse fab capacity.

      There are other reasons TSMC has had supply problems already. COVID, lack of water, earthquakes, etc.

        And that is happening. There are a dozen fabs that are supposed to start being built this year, and more have been declared to be on the way all over the world.

      Re: US Army plans to destroy world economy.

      You seem to be assuming that China invading Taiwan wouldn't be a disaster of epic proportions regardless. The "best" plausible outcome is one in which the invasion is so rapid, total, and successful that no opposition is possible; in that case TSMC's output will be reserved for China and everyone else (i.e., that "Western economy" you're worried about) will either get nothing or pay a premium price for heavily restricted supply. There are messier outcomes that lead to multilateral global war. always a sunny prospect. I'm afraid I don't see an outcome for Western economies that's appreciably better than the total annihilation of Taiwan's entire industrial base. The only thing I don't understand about this paper is why it was necessary to publish it; I'd have assumed this was already Taiwan's plan and that they had quietly made sure China was well aware of it. Denial of resources to an invading enemy isn't exactly a novel concept in warfare.

    4. big_D Silver badge

      Re: US Army plans to destroy world economy.

      And, with China ramping up investment in its own fabs, it would be in a key position to benefit from such a strategy, plus it would have all the talent that produced those chips, as they wouldn't be allowed to leave Taiwan after the invasion...

      They'd have the rest of the world over the proverbial barrel.

      I'd give the paper a very charitable E-.
