Twelve fellow Nobel Peace Prize laureates have written an open letter to President Barack Obama, urging the 2009 recipient of the award to finally close one of the "dark chapters" of recent U.S. history by first acknowledging, and then rejecting, the "flagrant use of torture and other violations of international law" that have been conducted in the name of "fighting terrorism" since 2001.

Written by the laureates as members of the Senate Intelligence Committee continue to press the White House and CIA on disclosing the findings of their investigation into some of the worst practices of inhumane treatment during the presidency of George W. Bush, the letter argues that the damage done by these acts has been not been isolated to the individual victims of U.S. torture.

"When a nation’s leaders condone and even order torture, that nation has lost its way," the letter states. "One need only look to the regimes where torture became a systematic practice – from Imperial Japan and Nazi Germany to the French in Algeria, South Vietnam, the Khmer Rouge and others – to see the ultimate fate of a regime so divorced from their own humanity."

The laureates continue, "As torture continues to haunt the waking hours of its victims long after the conflict has passed, so it will continue to haunt its perpetrators."

In addition to pressing for an overall commitment to disclose and disavow the torture practices conducted by the CIA and other agencies, the signers of the letter suggest President Obama take four specific steps in order to begin to repair the damage such actions have had on the nation and the world. They include:

Full disclosure to the American people of the extent and use of torture and rendition by American soldiers, operatives, and contractors, as well as the authorization of torture and rendition by American officials.

Full verification of the closure and dismantling of ‘black sites” abroad for the use of torture and interrogation.

Clear planning and implementation for the closure of Guantanamo prison, putting an end to indefinite detention without due process.

Adoption of firm policy and oversight restating and upholding international law relating to conflict, including the Geneva Convention and the UN Convention against Torture, realigning the nation to the ideals and beliefs of their founders – the ideals that made the United States a standard to be emulated.

In addition to South Africa's Archbishop Desmond Tutu and former President of East Timor José Ramos-Horta—who won the Nobel Prize in 1984 and 1996 respectively and spearheaded the effort—the letter was signed by ten other laureates, including: Mohammad ElBaradei of Egypt, 2005; Leymah Gbowee, Liberia, 2011; Muhammad Yunus, Bangladesh, 2006; Óscar Arias Sanchez, Costa Rica, 1987; John Hume, Northern Ireland, 1998; F. W. de Klerk, South Africa, 1993; Jody Williams, United States, 1997; Bishop Carlos X. Belo, East Timor, 1996; Betty Williams, Northern Ireland, 1976; and Adolfo Pérez Esquivel, Argentina, 1980.

The New York Times, which received an advance copy of the letter on Sunday, reports:

After the Bush administration revealed its narrow interpretation of the treaty in 2005, Congress enacted a statute banning cruel treatment anywhere. Mr. Obama ordered strict compliance with the statute when he took office in 2009. But the Obama administration has never taken an official stance on the whether the treaty separately imposes legal obligations abroad. It must do so in a presentation before the U.N. next month. State Department officials are pushing to abandon the Bush-era interpretation, but military and intelligence lawyers are objecting, arguing that doing so could have operational impacts and that more study is required.

The letter itself follows:

President Barack Obama

The White House

1600 Pennsylvania Avenue NW

Washington, DC 20500 Dear Mr. President, The open admission by the President of the United States that the country engaged in torture is a first step in the US coming to terms with a grim chapter in its history. The subsequent release of the Senate Select Committee on Intelligence summary report will be an opportunity for the country and the world to see, in at least some detail, the extent to which their government and its representatives authorized, ordered and inflicted torture on their fellow human beings. We are encouraged by Senator Dianne Feinstein’s recognition that “the creation of long-term, clandestine ‘black sites’ and the use of so-called ‘enhanced-interrogation techniques’ were terrible mistakes,” as well as the Senate Committee’s insistence that the report be truthful and not unnecessarily obscure the facts. They are important reminders that the justification of the torture of another human being is not a unanimous opinion in Washington, or among Americans as a whole. We have reason to feel strongly about torture. Many of us among the Nobel Peace Prize laureates have seen firsthand the effects of the use of torture in our own countries. Some are torture survivors ourselves. Many have also been involved in the process of recovery, of helping to walk our countries and our regions out of the shadows of their own periods of conflict and abuse. It is with this experience that we stand firmly with those Americans who are asking the US to bring its use of torture into the light of day, and for the United States to take the necessary steps to emerge from this dark period of its history, never to return. The questions surrounding the use of torture are not as simple as how one should treat a suspected terrorist, or whether the highly dubious claim that torture produces “better” information than standard interrogation can justify its practice. Torture is, and always has been, justified in the minds of those who order it. But the damage done by inflicting torture on a fellow human being cannot be so simplified. Nor is the harm done one-sided. Yes, the victims experience extreme physical and mental trauma, in some cases even losing their lives. But those inflicting the torture, as well as those ordering it, are nearly irreparably degraded by the practice. As torture continues to haunt the waking hours of its victims long after the conflict has passed, so it will continue to haunt its perpetrators. When a nation’s leaders condone and even order torture, that nation has lost its way. One need only look to the regimes where torture became a systematic practice – from Imperial Japan and Nazi Germany to the French in Algeria, South Vietnam, the Khmer Rouge and others – to see the ultimate fate of a regime so divorced from their own humanity. The practices of torture, rendition and imprisonment without due process by the United States have even greater ramifications. The United States, born of the concept of the inherent equality of all before the law, has been since its inception a hallmark that would be emulated by countries and entire regions of the world. For more than two centuries, it has been the enlightened ideals of America’s founders that changed civilization on Earth for the better, and made the US a giant among nations. The conduct of the United States in the treatment of prisoners through two World Wars, upholding the tenets of the Geneva Convention while its own soldiers suffered greatly from violations at the hands of its enemies, again set a standard of treatment of prisoners that was emulated by other countries and regions. These are the Americans we know. And believing that most Americans still share these ideals, these are the Americans we speak to. In recent decades, by accepting the flagrant use of torture and other violations of international law in the name of combating terrorism, American leaders have eroded the very freedoms and rights that generations of their young gave their lives to defend. They have again set an example that will be followed by others; only now, it is one that will be used to justify the use of torture by regimes around the world, including against American soldiers in foreign lands. In losing their way, they have made us all vulnerable. From around the world, we will watch in the coming weeks as the release of the Senate findings on the United States torture program brings the country to a crossroads. It remains to be seen whether the United States will turn a blind eye to the effects of its actions on its own people and on the rest of the world, or if it will take the necessary steps to recover the standards on which the country was founded, and to once again adhere to the international conventions it helped to bring into being. It is our hope that the United States will take the latter path, and we jointly suggest that the steps include: a. Full disclosure to the American people of the extent and use of torture and rendition by American soldiers, operatives, and contractors, as well as the authorization of torture and rendition by American officials. b. Full verification of the closure and dismantling of ‘black sites” abroad for the use of torture and interrogation. c. Clear planning and implementation for the closure of Guantanamo prison, putting an end to indefinite detention without due process. d. Adoption of firm policy and oversight restating and upholding international law relating to conflict, including the Geneva Convention and the UN Convention against Torture, realigning the nation to the ideals and beliefs of their founders – the ideals that made the United States a standard to be emulated.
