There 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.

Once the attacks occur, as we learned on Sept. 11, it is too late. It makes little sense to deprive ourselves of an important, and legal, means to detect and prevent terrorist attacks while we are still in the middle of a fight to the death with al Qaeda.

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.

Punishing abuse in Iraq should not return the U.S. to Sept. 10, 2001, in the way it fights al Qaeda, while Osama bin Laden and his top lieutenants remain at large and continue to plan attacks.

I believe that the power to declare war is most important in limiting the powers of the national government in regard to the rights of its citizens, but that it does not require Congress to give its approval before the president uses force abroad. I do not believe that the framers of the Constitution understood the power to declare to mean "authorize" or "commence" war. That does not mean that the separation of powers or checks and balances will not work.

We can guess that the unacceptable conduct of the soldiers at Abu Ghraib resulted in part from the dangerous state of affairs on the ground in a theater of war.
