On ABC News last weekend, former Vice President Dick Cheney confessed to playing a key role in the commission of war crimes during the Bush administration.

"I was a big supporter of waterboarding," boasted Cheney.

Waterboarding is torture and a war crime. The UN Convention on Torture, the Geneva Conventions, the Red Cross, and constitutional governments around the globe agree on this point of law. More to the point, Attorney General Eric Holder has stated publicly that waterboarding is torture. Cheney's confession legally obligates Holder to prosecute him.

Cheney apologists will no doubt turn a blind eye to this. But this is the law, plain and simple. The case has been laid out in detail by Andrew Sullivan​, Glenn Greenwald, and Scott Horton.

By publicly confessing his role in illegal U.S torture programs, Cheney has created an extraordinary opportunity to hold the Bush administration accountable for its crimes. One that must not -- and indeed legally cannot -- be ignored.

Tell Attorney General Holder that he must prosecute Dick Cheney for torture.
