It is important to recognize the differences between the war in Iraq and the war on terrorism. The treatment of those detained at Abu Ghraib is governed by the Geneva Conventions, which have been signed by both the U.S. and Iraq.
John YooThere are pros and cons about the policy decision whether to follow the Geneva Conventions in a war where they do not legally apply. Among the pros might be benefits for America's image, its ability to argue in future conflicts that the Conventions should be followed, and training soldiers to follow only the Geneva standards. Among the cons might be greater security and safety for our troops who capture and detain al Qaeda operatives and the ability to gather more actionable intelligence swiftly.
John YooThe United States is at war with the al Qaeda terrorist group. Al Qaeda is not a nation-state and it has not signed the Geneva Conventions. It shows no desire to obey the laws of war; if anything it directly violates them by disguising themselves as civilians and attacking purely civilian targets to cause massive casualties.
John YooPersonally, I do not think that torture is necessary. But it may be the case that interrogation methods that go beyond questioning, but do not arise to the level of torture, may be necessary to get actionable intelligence from high-ranking al Qaeda leaders
