TSMC begins producing 4-nanometer chips in Arizona

Sure, but coming dead last behind Taiwan, Korea, US, Japan and China in the race to cutting edge semiconductor manufacturing is nothing to brag about. That's like celebrating getting the consolation prize for coming last.

This means you're getting the lowest industry margins, meaning less profits, less money for R&D, less wages and also less geopolitical leverage. This is nothing to celebrate but should be an alarm clock for our elected leader to wake the f up.

A lot of semi research is done in the EU, like at IMEC in Belgium, but few of it ends up commercialized by EU companies, so EU taxpayer money gets spent but other nations get to reap the rewards.

The US would probably defend Taiwan if the CCP invaded it. I don't think we would ever use nukes.

But being the "policeman of the world" has helped with preserving dollar's status as the major currency for international transactions between third countries, and in particular for oil, which in turn makes the dollar a desirable currency, because everyone has and wants to have dollars, and has allowed the federal central bank to print the trillions of dollars it had been printing over and over without it losing its value. Any other country's currency would have been super-inflated if they did the same.

> Lots of bad decisions but the world also takes for granted the open seas, etc. that come at a great cost to Americans in reduced social services like health insurance and higher education.

Thanks for the laugh

Nonsense, Americans pay the most for health insurance. It's merely about how you use the money. Same with education. The American economy is so great it could afford an entire second military industrial complex and still have enough money left for healthcare and education.

Firstly, you don't need to spend America levels (more than than the next world powers combined) to have an efective military deterrent, since currently most EU member states barely spend 2% GDP on defense which is too little. You can have a strong military AND welfare services if you're smart about your state finances which many EU members are not(looking at you Germany), especially since defense investments create more jobs and innovations flowing back into the state coffers. Switzerland is a good example.

Secondly, America's defense is way more expensive than it needs to be due to a lot of high level corruption and lobbying from the military industrial complex profiteering when it comes to purchasing decisions, where a 10$ bag of bolts is bought by the military for 50K$, shovelings taxpayer money into the right private industry pockets. EU can achieve similar results with way less cost if it wanted to by minimizing this style of corruption but that's easier said than done. The only one rivaling America's military inefficiency is Germany who spends more than France, a nuclear power with aircraft carriers, but can't afford to issue underwear and dog tags to new conscripts.

Thirdly, America's lack of social services is not due to its powerful military, but due to political choices and inefficiencies. It could easily have better welfare if it wanted to since it can afford it with the world's largest GDP, but it chooses not to, since the current status quo is enriching a lot of private enterprises and parasites, while the concept of even more welfare is usually not a popular topic with the US voters which see welfare recipients as lazy and an unnecessary money sink funded by higher taxes on the middle class which they don't want. So their issue is social and political, not economical.

Selling the secret sauce to US definitely make Taiwan disposable. But I also bet TSMC doesn't have a choice as whoever in power in US can also impose sanction/tariff or whatever they can to make TSMC to compile.

TSMC being 2-4 years ahead of Samsung/Intel has nothing to do whether US would be willing to go on a nuclear war and move the entire world decades if not millenias back. No one can go on a direct war with a country with nukes unless they are ready for mutually assured destruction.

Short of nuclear weapons, I'm not sure what would allow Ukraine to "win". Even given all the hardware, Ukraine doesn't have the staff or experience to field a full NATO air wing and integrate it to fight according to NATO combined arms doctrine -- if that even WOULD produce a "win" (there is an untested assumption that a NATO-standard military could trounce Russia)

> they’ll be willing to let China have the islands now too

The islands are Chinese. The US back Taiwan as an anti-communist and anti-China (divide and conquer) tactic, including because its location. If the communists had lost the civil war, the mainland and Taiwan would all have remained under ROC control and it would have been interesting to see what the US would have come up with, instead (academic and thought experiment but interesting to imagine nonetheless).

In Ukraine the US don't want to be dragged in a war against Russia and things have played well for them so far (really the US are the only winners so far).
