The arabic world is about tribalism. The African world is about tribalism. The Muslim religion isn't the only factor contributing to violent conflict in the Middle East and Africa. Even Sri Lanka is tribal warfare. Relgion plays a role but isn't the only cause of conflict.
Extremist Islam is merely an overlay (and a recent one at that) atop the primal, unchanging mind-set of the East, which is tribalism, and its constituent individual, the tribesman.
Tribalism and the tribal mind-set are what the West is up against in Hezbollah, Al Qaeda , the Iraqi insurgency, the Sunni and Shiite militias, and the Taliban.
What exactly is the tribal mind-set? It derives from that most ancient of social organizations, whose virtues are obedience, fidelity, warrior pride, respect for ancestors, hostility to outsiders and willingness to lay down one's life for the cause/faith/group. The tribe's ideal leader is closer to Tony Soprano than to FDR and its social mores are more like those of Geronimo's Apaches than the city council of Scarsdale or Shepherd's Bush.
Can the tribal mind embrace democracy? Consider the contrast between the tribesman and the citizen:
A citizen is an autonomous individual. A citizen is free. A citizen possesses the capacity to evaluate the facts and prospects of his world and to make decisions guided by his own conscience, uncoerced by authority. A congress of citizens acting in free elections determines the political course of a democratic community.
A citizen prizes his freedom; therefore he grants it to others. He is willing to respect the rights of minorities within the community, so that his own rights will be shielded when he finds himself in the minority.
The tribesman doesn't see it that way. Within the fixed hierarchy of the tribe, disagreement is not dissent (and thus to be tolerated) but treachery, even heresy, which must be ruthlessly expunged. The tribe exists for itself alone. It is perpetually at war with all other tribes, even of its own race and religion.
The tribesman deals in absolutes. One is either "of blood" or not. The enemy spy can infiltrate the tribal network no more than a prison guard can worm his way into the Aryan Brotherhood. The tribe recognizes its own. It expels (or beheads) the alien. The tribe cannot be negotiated with. "Good faith" applies only within the pale, never beyond.
The tribesman does not operate by a body of civil law but by a code of honor. If he receives a wrong, he does not seek redress. He wants revenge. The taking of revenge is a virtue in tribal eyes, called badal in the Pathan code of nangwali. A man who does not take revenge is not a man. Al Qaeda , Hezbollah, and the sectarian militias of Iraq are not in the war business, they are in the revenge business. The revenge-seeker cannot be negotiated with because his intent is bound up with honor. It is an absolute.
Perhaps the most telling difference between the citizen and the tribesman lies in their views of the Other. The citizen embraces multiplicity; to him, the melting pot produces richness and cultural diversity. To the tribesman, the alien is not even given the dignity of being a human being; he is a gentile, an infidel, a demon.
