"We may translate, “Oderint dum metuant” as, “Let them hate, so long as they fear.” It is the precise opposite of, “Win their hearts and minds.” And it is, once again, an attitude blessedly free of that panic which, I think, all Western policy towards the “Islamist” terror threat is now tending, starting with flight from Iraq.

What the older “just-war theorists” knew, or learned (starting with St Augustine, if you read his successive prescriptions for dealing with violent schismatics), is that war is ruthless. The very humane Clausewitz taught, that the war leader unprepared to be as ruthless as his enemy does not bring peace. He creates a quagmire, and his hesitations lead finally to defeat. The chemo-therapist does not negotiate with a cancer, nor grant it the benefit of the doubt. He does not weep for all the hairs that will fall out.
As to the enemy we presently face -- the same in the Sunni Triangle as over Manhattan in September, 2001 -- we cannot win their hearts and minds in the foreseeable future. They do not love us. Therefore let them hate, so long as we can make them fear us more than we fear them."
