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.

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.

Congress's definition of torture in those laws - the infliction of severe mental or physical pain - leaves room for interrogation methods that go beyond polite conversation.

Human rights advocates, for example, claim that the mistreatment of Iraqi prisoners is of a piece with President Bush's 2002 decision to deny al Qaeda and Taliban fighters the legal status of POWs under the Geneva Conventions.

It is also worth asking whether the strict limitations of Geneva make sense in a war against terrorists.

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.

Without territory, it does not even have the resources to provide detention facilities for prisoners, even if it were interested in holding captured POWs.
