After 9/11. it became common for commentators to recline wisely on their armchairs and say, "Ah, but what Islam needs is a reformation." Deeper details were rarely forthcoming, and many nuances went quite unexplored.
Well, Fareed Zakaria, in the latest installment of his column in Newsweek, says that the reformation has begun and "it's been marked by calumny, hatred and bloody violence." Do read the full piece, "The Road to Reformation," it's quite excellent.
