Pacifism in the face of war is not only irresponsible - it is immoral. Refusing to meet force with force in the name of peace will beget not peace, but further death and destruction, the very violence the pacifists seek to avoid.
It is not the conservative psyche that needs analysis. Conservatives were right in the Cold War --so right that liberals are pretending they were with us all along -- and they are right about Iraq. It is Leftists who need to account for their consistently disgraceful positions throughout the Cold War and into the War on Terror.
There is no incompatibility between moral clarity and intellectual firepower, between faith in God and humility -- in fact, they're mutually dependent, between a strong conviction that we must go to war and an abundant compassion for any that may die as a result, and between political conservatism and personal decency.
