“The United States participated actively and effectively in the negotiation of [this] Convention. It marks a significant step in the development during this century of international measures against torture and other inhuman treatment or punishment. Ratification of the Convention by the United States will clearly express United States opposition to torture, an abhorrent practice unfortunately still prevalent in the world today.

The core provisions of the Convention establish a regime for international cooperation in the criminal prosecution of torturers relying on so-called ‘universal jurisdiction.’ Each State Party is required either to prosecute torturers who are found in its territory or to extradite them to other countries for prosecution,” – Ronald Reagan’s signing statement on the ratification of the UN Convention on Torture.

Allow me to repeat:

Each State Party is required either to prosecute torturers who are found in its territory or to extradite them to other countries for prosecution.
