Go to any mosque in the West (let alone in the Islamic countries) on any Friday and you are sure to hear a litany of woes about how the "cross-worshippers" have allied themselves with the "plotting Jews" in order to destroy Islam, which, as God's final message, is the only true faith.

You will hear how the West is mired in corruption, its womenfolk exposing their midriff in public and its governments sanctioning gay and lesbian marriages. You will also hear how "the Crusaders" have invaded Muslim lands and are trying to impose their democratic system on Afghanistan and Iraq.

Such a discourse might leave most Muslims indifferent or even annoyed. But it is enough for it to seduce even 1 percent of the world's Muslims — that is to say a cool 13 million people — for everyone to be in trouble.
