Read this Statement by the President of the United States of America from last June. It was written for the United Nations International Day in Support of Victims of Torture. Here's an excerpt.
Torture anywhere is an affront to human dignity everywhere. We are committed to building a world where human rights are respected and protected by the rule of law.
The United States is committed to the world-wide elimination of torture and we are leading this fight by example.
