USA don't appear to be worried about letting such things as jurisdiction and sovereignty of other states interfere with their application of various USC.

tptacek's post (http://news.ycombinator.com/item?id=4812735, '[located outside the United States but using it in a manner that affected interstate or foreign commerce or communication of the United States];') and other info on the statute appears to show that the law is extended to those that cause detriment to US trade from anywhere.
