“A substantial amount of money has gone,” Lamido Sanusi told a Nigerian Senate committee in January. How much money? A cool $20 billion. Where did it go? That is the question no one can—or will—answer.Sanusi was, until recently, the governor of Nigeria’s central bank. He showed the Senate committee how much money was missing and told them he feared that the economy might collapse if these funds weren’t recovered. “I wasn’t just talking about numbers. I showed it was a scam,” he told Adam Nossiter of the New York Times in a recent interview. He threatened banking officials with a special investigation. He accused the national oil company of disguising and disappearing its revenues. Never before had Nigerian officials been subjected to this sort of scrutiny from such a high-ranking official. One unnamed banker said Sanusi’s accusations caused a panic, “a general heaviness.” Sanusi was told to “cool down.” A few weeks later, Nigeria’s president fired him.Sanusi is only the latest rabble-rouser to accuse Nigeria’s elite of skimming and stealing billions of dollars from the country’s oil revenues. That $20 billion in oil sales could just disappear from the treasury boggles the mind. But Nigeria’s political elite shuts up tight as soon as someone like Sanusi asks questions. With an election coming up, and Nigeria’s political system dependent entirely on patronage money, no answers are likely to be forthcoming.As if a deeply corrupt government weren’t enough of a burden on the country, Boko Haram is again on the forward march. According to one Nigerian newspaper Boko Haram has killed almost 600 people since January 16. On that day, President Goodluck Jonathan replaced all the heads of the military with their deputies, whom he hoped could more capably deal with the insurgency. That plan hasn’t gone particularly well. Not even a week ago militants attacked a school, shot and killed 43 students, and abducted an untold number of women. Not for the first time, schools across the northeast were closed by the government to prevent further deaths.
