Going by this logic, why doesn't the US kneecap European, South Korean, Japanese, or Taiwanese companies that are competitive with US companies in those industries?

They key difference (outside of China being more adversarial in general) is that Chinese companies like Huawei blatantly steal IP from companies in those countries to make their tech.

Also, Huawei is essentially an arm of China's intelligence apparatus, so keeping them at a far distance from other counties' infrastructure is generally a good idea.

This isn't a protectionist thing, it's a corporate espionage and national security thing.

Just because a company is located in Europe, south Korea, japan etc doesn't mean its a European, south Korean, Japanese etc company.

Look into their supply lines you will find that the core components are most likely US made so they have those companies by their balls. Or look into ownership breakdown might be that big US finance pretty much owns the companies voting wise.

Took ASML the core component the light source is a US product, with out that product ASML can't produce their EUV devices.

Interesting, where can I read about this light source that’s a US-made product?

In 2012 ASML took over the San Diego based CYMER which creates the light source for ASML EUV machines.
