The reason they convened a national conference to discuss Nigeria's future this month is that it's the 100th anniversary of the unification of the northern and southern protectorates into one nation. Well, one colony, actually, since the whole place would remain under British rule for another half-century. And the one
A century of dysfunction

Sanusi, who was named Central Bank Governor of the Year in 2010 by Banker magazine, was promptly accused of links to Boko Haram in a document circulated to Nigerian websites that was traced back to President Jonathan's social media adviser. It was a typical establishment response, and it was total nonsense. But a depressing number of southern Nigerians will believe almost anything about Sanusi simply because he is a northern Muslim.
He is actually a member of the northern aristocracy - his grandfather was the emir of Kano - and an Islamic scholar who condemns Wahhabist fundamentalism. He is one of Nigeria's foremost advocates of a tolerant, inclusive Islam: "Even a cursory student of Islamic history knows that all the trappings of gender inequality present in the Muslim society have socio-economic and cultural - as opposed to religious - roots," he said recently.
Yet the mistrust between Muslims and Christians, northerners and southerners, is so great that Sanusi's whistle-blowing is seen by many southerners as a political operation aimed at the Christian president. They believe this even though they also know that the money really was stolen by people at the NNPC, and that Goodluck Jonathan is protecting them because some of it was going to be used to finance his re-election campaign next year.
And why does Jonathan need so much money? To buy the support of the northern power-brokers, who will then deliver the votes to keep him in the presidency. Then he will be able to go on protecting his friends. It's a closed system, and it's making Sanusi more radical by the moment.
But Sanusi is unlikely to bring the system down. That is why, at the National Conference on Nigeria's future that meets in Abuja over the next three months, some people will certainly defy the ban and start talking about redividing Nigeria between north and south. They will mostly be southerners, who resent the large amounts of oil income that the federal government transfers to the northern states that desperately need the money.
Northerners will fiercely resist the idea of partition because they would be left running a country only slightly better off than Mali. (Despite the transfers of oil revenue, 72 per cent of the population in the North lives in poverty; in the South, only 27 per cent does.) And in the end, nothing will happen, because cutting off the North would spoil the game.
Nigeria is unquestionably the most dysfunctional large country in the world, but it will hang together because all the elites benefit from the dysfunction, which allows them to steal massive amounts with complete impunity.
Indeed, you might say that Nigeria survives because it is dysfunctional.
