When Arabs promise to destroy Israel or turn American and European cities into infernos with rivers of blood running along the streets, I don't question their sincerity: as soon as they think they can do it, they will try. In most other matters, I tend to distrust them. I certainly get suspicious whenever it comes to numbers. It's not just because the so-called “Arabic numerals” were in fact invented by Hindus. It's mainly because the Islamic concepts of good and evil can be exhaustively described in a single sentence: Whatever is good for jihad is good, period.
