Succinctness on the NYT op-ed page, from Thursday:
The war in Iraq and the war on terrorism are ultimately political in character. Victory depends in the end not on technology or on overwhelming force but on political persuasion. By using torture, the country relinquishes the very ideological advantage - the promotion of democracy, freedom and human rights - that the president has so persistently claimed is America's most powerful weapon in defeating Islamic extremism. One does not reach democracy, or freedom, through torture.
By using torture, we Americans transform ourselves into the very caricature our enemies have sought to make of us. True, that miserable man who pulled out his hair as he lay on the floor at Guantanamo may eventually tell his interrogators what he knows, or what they want to hear. But for America, torture is self-defeating; for a strong country it is in the end a strategy of weakness. After Mr. Gonzales is confirmed, the road back - to justice, order and propriety - will be very long. Torture will belong to us all.
