Two countries having different laws says nothing inherent about the need to "limit" the power of one to enforce a specific set of laws within their borders, unless We assume the U.S. is inherently Exceptional compared to other countries, and so if another country has some weird hang-up that threatens Our Economy, it is quite concerning and really the citizens need to rise up against their leaders' tyranny and ensure U.S. Law is truly global before one of Our Corporations loses some Money.
