Isn't the WT an "international" organization?

Promoting justice by prosecuting human rights violators and other international criminals
The Human Rights and Special Prosecutions Section (HRSP) primarily investigates and prosecutes cases against human rights violators and other international criminals. HRSP investigates and prosecutes human rights violators for genocide, torture, war crimes, and recruitment or use of child soldiers, and for immigration and naturalization fraud arising out of efforts to hide their involvement in such crimes. HRSP also prosecutes perpetrators of other international violent crimes, particularly those involving the Military Extraterritorial Jurisdiction Act (MEJA) or occurring within the Special Maritime & Territorial Jurisdiction of the United States (SMTJ). Finally, HRSP prosecutes members of international criminal networks who seek to evade our immigration laws, such as by smuggling persons into the United States. In addition to its prosecutorial activities, HRSP is actively engaged in policy work, both domestically and internationally.
