Personally, 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

It has never demonstrated any desire to provide humane treatment to captured Americans. If anything, the murders of Nicholas Berg and Daniel Pearl declare al Qaeda's intentions to kill even innocent civilian prisoners.

The United States has used force abroad more than 130 times, but has only declared war five times - the War of 1812, the Mexican-American War, the Spanish-American War, and World Wars I and II.

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.

I think it can be very important for the president to seek congressional approval for war , even though not constitutionally required to do so, in certain situations. It makes sense to go to Congress to signal our national resolve and our willingness to fight to defend other nations or the freedom of their peoples.

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.

This is not to condone torture, which is still prohibited by the Torture Convention and federal criminal law.
