Yes, we should do all we can to win our battles; we can’t afford not to. But giving up our values will not help us win. It will only cost us our self-respect and the morale of our soldiers. To take on the values of our enemies is to surrender to them, to become them. Is that what we want to do? Certainly it’s what our enemies want us to do. Many in the Arab countries would love for us to sink into barbarism and so lose both reason to fight and the means of doing so. They know that our flourishing economy gives us a material advantage over any combination of Arab states. But all this is built on love of life, not death.
