If we're talking about targeted hacks, are we sure the US doesn't do this? Is US soil off limits for hacks somehow? What plausible exploits could be done when someone is on US soil, but not over the internet, especially on modern phones where the baseband is isolated?

I'm not making any subjective or moral judgement. I'm an american who lives and works in the US, so there are a wide variety of ways law enforcement or others can get data from me, and a variety of legal protections that make certain risks unlikely.

TBH, I don't know what the US does or doesn't do, and if I was visiting the US as a citizen of another country, I'd think about risks from the perspective of my experience.
