George W. Bush is insisting that the torture of humans is legal and defended his use of techniques widely believed to be torture, such as simulated drowning, in violation of American and international law. This is now grounds for impeachment because the President has knowingly violated the law and our international treaty obligations. It is also inhumane and subverts all which America has stood for decades: the victory of good over evil. Now we are just as bad as the terrorists. Wow, something to truly be proud of!
Waterboarding is NOT legal. It is torture and very generally agreed upon by experts to be torture. Even Attorney General Mukasey has described it as torture. Our country has prosecuted others for practicing this form of "enhanced interrogation technique" and anyone committing the act is guilty of a war crime.
Furthermore, in addition to simply being inhumane, torture has been proven ineffective. Right wing noise machine practitioners love a scenario where a nuclear device is set to explode in or near an American city (apparently the farms don't matter) and ask whether we would torture a terrorist to discover its location. Actually that would be the worst thing to do because torture almost always provides false information. Valuable time would be lost chasing down the blind alleys resulting from information given simply to stop the torture.
We saw this repeatedly in 2004 with periodic terror alerts which resulted from the water boarding of a major terrorist. He told his interrogators whatever he thought they wanted to hear. This is the pattern of every torture session. Billions were spent guarding against ephemeral dangers. People were put in danger and the public was subjected to anxiety and fear unnecessarily (except for the political gains which proved considerable for Republican fear mongerers).
Skilled interrogators don't need torture to gain valuable, true information.
I keep going back to this video of General Wes Clark on the subject:
