"...Ever since it was spun off from al-Qaida some 10 years ago, Isis has made clear its commitment to beheading apostates and unbelievers, enslaving women and wiping out communities that will not submit to its ultra-fundamentalist interpretation of Islam. In its carefully crafted internet videos, it has advertised these crimes itself. There has never been any doubt that Isis practises methodical savagery as an integral part of its strategy of war. This did not prevent an abortive attempt on the part of the American and British governments in August of last year to give military support to the Syrian rebels – a move that could have left Isis the most powerful force in the country. Isis became the prime enemy of western governments only when it took advantage of the anarchy these same governments had created when they broke the state of Iraq with their grandiose scheme of regime change.Against this background, it would be easy to conclude that talk of evil in international conflicts is no more than a cynical technique for shaping public perceptions. That would be a mistake. (Tony) Blair’s secret – which is the key to much in contemporary politics – is not cynicism. A cynic is someone who knowingly acts against what he or she knows to be true.

It’s not that they are obsessed with evil. Rather, they don’t really believe in evil as an enduring reality in human life. If their feverish rhetoric means anything, it is that evil can be vanquished. In believing this, those who govern us at the present time reject a central insight of western religion, which is found also in Greek tragic drama and the work of the Roman historians: destructive human conflict is rooted in flaws within human beings themselves. In this old-fashioned understanding, evil is a propensity to destructive and self-destructive behaviour that is humanly universal. The restraints of morality exist to curb this innate human frailty; but morality is a fragile artifice that regularly breaks down. Dealing with evil requires an acceptance that it never goes away... "
