Yes, you are right there is no world government...I was speaking as to how business is done internationally; something that is getting better and better for copyright holders. US or, for that matter, EU country copyright law has a very long reach indeed. The copyright holder can sue even international defendants in US court (there are suits pending against many Chinese companies for this very thing for knockoff software and music). A foreigner can't hide behind lack of a treaty to prevent a judgment in US court, even if you live in some hostile country like Iran (which has little or no diplomatic relations with the US). Think of the 9-11 plaintiff's wrongful death suits against Osama bin Laden. Where is he?...well he's not exactly going to show up in a US court.
Good luck collecting you say? If the violator doesn't appear in court, a default judgment is entered and even if the plaintiff can't collect right now, the pirate had better stay away from all US ports and countries *with* treaties to enforce valid judgments (e.g. bank accounts, assets). Think it doesn't matter?...Just take a look at all those Iranian assets still frozen since 1979.
