<blockquote>From his signing statement ratifying the UN Convention on Torture from 1984:

"The United States participated actively and effectively in the negotiation of the 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.</blockquote>
