> It's at the very least debatable whether a country should have the ability to make laws that apply to foreigners in foreign countries.

That's a fair point. However if Huawei has a physical presence as a business in the US (which it does) then it should certainly be subject to obeying US laws. The one responsible for violating that law should be held responsible for breaking the law, whether they are a foreigner or not, in the same way that a tourist traveling to another country is still subject to that country's laws.
