Yeap, because they may have been facilitating U.S. citizens in breaking U.S. law on U.S. soil. Copyrights are also governed by international agreements, so there is a huge incentive for foreign governments to cooperate.

Now I don't agree with a government taking illegal actions on either home or foreign soils, and believe that they should be held accountable. However illegal activities have been conducted online for far too long simply because there is minimal accountability. (Law breakers can go to foreign soil to delay arrest and prosecution, or even seek nations that will protect them from arrest and prosecution.) So something needs to be done.
