Facing the truth is hard to do, especially the truth about ourselves. So Americans have been sorely pressed to come to terms with the fact that after 9/11 our government began to torture people, and did so in defiance of domestic and international law. Most of us haven't come to terms with what that meant, or means today, but we must reckon with torture, the torture done in our name, allegedly for our safety.

It's no secret such cruelty occurred; it's just the truth we'd rather not think about. But Memorial Day is a good time to make the effort. Because if we really want to honor the Americans in uniform who gave their lives fighting for their country, we'll redouble our efforts to make sure we're worthy of their sacrifice; we'll renew our commitment to the rule of law, for the rule of law is essential to any civilization worth dying for.

After 9/11, our government turned to torture, seeking information about the terrorists who committed the atrocity and others who might follow after them. Senior officials ordered the torture of men at military bases and detention facilities in Afghanistan and Iraq, in secret CIA prisons set up across the globe, and in other countries - including Libya and Egypt -- where abusive regimes were asked to do Washington's dirty work.

The best known of all the prisons remains Guantanamo on the southeast coast of Cuba. For years, the United States naval base there seemed like an isolated vestige of the Cold War -- defying the occasional threat from Fidel Castro to shut it down. But since 9/11, Guantanamo -- Gitmo -- has been a detention center, an extraterritorial island jail considered outside the jurisdiction of U.S. civilian courts and rules of evidence. Like the notorious Room 101 of George Orwell's 1984, the chamber that contains the thing each victim fears the most to make them confess, Guantanamo's name has become synonymous with torture. Nearly 800 people have been held there. George W. Bush eventually released 500 of them, sometimes after years of confinement and cruelty. Barack Obama has freed 67, but 169 remain, even though the president pledged to close the Guantanamo prison within a year of his inauguration. Now, forty-six are so dangerous, our government says, they will be held indefinitely, without trial.

We almost never see the detainees. Were it not for the work of human rights organizations and the forest of lawsuits that have arisen from our actions, the prisoners would be out of sight, out of mind. Five of the Guantanamo prisoners were recently arraigned before a military commission for their role in the attacks. One of them is Khalid Sheikh Mohammed, who says he was the mastermind behind 9/11. He was waterboarded by interrogators 183 times. Pentagon officials predict it will be at least another year before the five go on trial.

Earlier this month, lawyers for Mohammed al-Qahtani -- the so-called "20th hijacker" who didn't make it onto the planes -- filed suit in New York federal court to make public what they described as "extremely disturbing" videotapes of his interrogations. He was charged in 2008 with war crimes and murder, but the charges were dropped after the former convening authority for the Guantanamo military commissions, Susan Crawford, told journalist Bob Woodward that al-Qahtani's treatment "met the legal definition of torture."

He remains in indefinite detention, as does Abu Zubaydah, a Saudi citizen alleged to have run terrorist training camps. He was waterboarded at least 83 times in a single month. Just this week a federal appeals court refused to release information on the interrogation methods the CIA used on Abu Zubaydah and other terrorist suspects.

You may also have seen the flurry of action this month around a section of the new National Defense Authorization Act that allows the military to detain indefinitely not only members of al Qaeda, the Taliban and "associated forces" but anyone who has "substantially supported" them. A federal court struck down that provision in response to journalists and advocates who believe it could be so broadly interpreted it would violate civil liberties. Nonetheless, two days after the court's decision, the House of Representatives reaffirmed the original provision.

The other day, eight members of the Bush Administration -- including President Bush, Vice President Cheney, and Defense Secretary Rumsfeld -- were found guilty of torture and other war crimes by an unofficial tribunal meeting in Malaysia. The story was played widely in parts of the world press, with reports that the judgment could lead the way to proceedings before the International Criminal Court in The Hague. It received almost no mention here in the United States.

This summer, it's believed that the United States Senate's intelligence committee finally will release a report on "enhanced interrogation techniques," that euphemistic phrase for what any reasonable person not employed by the government would call torture. The report has been three years in the making, with investigators examining millions of classified documents. The news service Reuters says the report will conclude that techniques such as waterboarding and sleep deprivation do not yield worthwhile intelligence information.

So here we are, into our eleventh year after 9/11, still at war in Afghanistan, still at war with terrorists, still at war with our collective conscience as we grapple with how to protect our country from attack without violating the basic values of civilization -- the rule of law, striving to achieve our aims without corrupting them, and restraint in the use of power over others, especially when exercised in secret.

In future days and years, how will we come to cope with the reality of what we have done in the name of security? Many other societies do seem to try harder than we do to come to terms with horrendous behavior commissioned or condoned by a government. Beginning in 1996, in South Africa, the Truth and Reconciliation Commission held hearings at which whites and blacks struggled to confront the cruelty inflicted on human beings during apartheid.

And perhaps you caught something said the other day by the president of Brazil, Dilma Roussef. During the early 70's, she was held in prison and tortured repeatedly by the military dictators who ruled her country for nearly 25 years. The state of Rio de Janeiro has announced it will officially apologize to her. Earlier, when she swore in members of a commission investigating the dictatorship, President Roussef said: "We are not moved by revenge, hate or a desire to rewrite history. The need to know the full truth is what moves us."

In other words, "You shall know the truth and the truth shall make you free."

On this weekend's Moyers & Company (check local listings), PEN American Center's Larry Siems, author of The Torture Report, and movie director Doug Liman, whose credits include The Bourne Identity, Mr. and Mrs. Smith, and Fair Game, join Bill Moyers to talk about U.S. torture tactics and their collaborative multimedia effort Reckoning with Torture.
