Spy? Sort of. Generally speaking, US intelligence agencies have a lot of leeway when 1) you're not a US citizen AND 2) you're not on US soil. If either of those things isn't true then it's a different story. There are workarounds (eg outsourcing spying to allies).
Torture and kill? Huh? I'm not even sure what you're talking about. Do you mean in a war zone?
> Corporations are an extension of the state
If anything, I'd argue in the US the government is an extension of the corporations. The US government certainly acts at the behest of the capital-owning class.
> They have no choice but to facilitate the use of state power on foreign nationals.
I mean US companies are subject to US laws and that includes (as stated) pen registers, NSLs, FISA warrants, etc. Still, there's more due process here than for Chinese companies.
> If you are an American all you're saying is "only my government should spy on me".
That's not what I said at all.
What I will say is that given the choice between living in China and being subject to Chinese spying and living in the US subject to US spying I'll pick the US hands down every time.
Why? Because I can talk about US atrocities without "disappearing". I could compare the president to a cartoon character without "disappearing". The US also doesn't (currently at least) engage in ethnic cleansing and eradication through "re-education" camps (eg Tibet, Xianjiang). Nor do I have to worry about my ability to get anywhere because I said something critical of the government and took a big hit to my social credit score. And the US has no equivalent to Hong Kong's "security" laws.
