Depends what you mean. US law takes into account the existence of foreign nations already; some explicitly end at the borders, others not so.

It also depends on which country, and to what extent agreements exist between those countries wrt policing their own territories. Those that don't have such agreements, are often also limited in what extent they can do business in the US.

GP didn't say anything like that. They were talking about

> avoid[ing] local laws

(i.e. legally) which is a whole different matter.

How is that different from saying Swedes can avoid Swedish law by incorporating somewhere else?

This is not what you said. You were talking about "a company that violates US law" (emphasis mine).
