Wouldn't it be enough that someone located not-in-the-US to do any sort of business with a person in the US, for the US government to now consider that part of their jurisdiction and get involved? Just one random example from Wikipedia, but there are a bunch more cases of the US acting "outside of their jurisdiction": https://en.wikipedia.org/wiki/Shutdown_of_Sky_Global

Similarly, I guess North Korea could look at things the same way.
