The copyright violation is coming from a server hosted in the US, so it's subject to US laws.
It would be the same if I took a DVD from the US that doesn't have a copyright in another country, went to that country to copy it, and then tried to sell it back in the US. It doesn't matter where I'm making the copy, it matters where I'm distributing it.
