No, no, no. The U.S. Gov. does not contend this. The DOJ believes the U.S. has jurisdiction over the Neteller transactions due to the amount of contact those transactions had within the geography of the US. Namely, the people sending and receiving $ to and from Neteller were physically located in the US when doing so. While I disagree (and I believe the WTO does also, although I'm not completely up on its recent decisions) with its position, that is the basis upon which the DOJ uses to charge offshore operations doing business with US customers. The US Gov does not believe, as you imply, that people doing drugs in Holland are breaking US drug laws. You can be a prostitute in Amsterdam, and then come to the US without being prosecuting for your actions that had no contact or involvement with the US.
Forgive me if I sound didactic, and maybe you meant precisely what I wrote above. And regardless, I think you and I are on the same side on this one!
