Massive read. Considerably more important than probably 95% of the appalling sewage most of us usually read. I am frankly ashamed to have been in such profound ignorance of these things, although that comes as no surprise (neither is that to say that my ignorance is altogether gone).
Mention has been made of the fact that the general drift of the book seems to be in the direction of 9/11 from the get-go (it was published in 2002), but the authors do address this in the last chapter, saying that their intention was not to make it seem as though the attacks were the direct result of the foundation of Islam or any such 1-to-1 sentential stupidity (as in: "if P then Q"). Rather, the authors "intended mainly to demonstrate the historical diversity of the Middle East, and to suggest the other histories that might have unfolded as well as explore the one that did come to pass." This is a fair point, however badly expressed.
To put it another way: whatever we know now about the Crusades, for example, has for the most part passed into the realm of the mythic past and become the stuff of romance. But the attacks of September 11th are, needless to say, modern and consequently very real. And without the context of our present world to anchor it, study of the past can often be too abstract to be appreciable to us, or of any real use in deciding the route that we must take toward the future.
There is a series of videos on Youtube, for the time being, which I certainly won't be able to link here on GR, but they're of a debate at Oxford on the motion that "Islam is a peaceful religion." Of special interest are those arguments made by Daniel Johnson (insofar as it represents an opinion common to many secular people all over the world) & Mehdi Hasan, whose warranted excitement at the time does not withstand in the least his astonishing eloquence & hugely impressive intellect. Those interested in the old, sophisticated, and prodigiously successful faith of the Arabs (which of course now is practiced by millions upon millions of Turks, Mongols, Iranians, Chinese, Chechens, Circassians, and many others) will no doubt derive some benefit from them.
But then, anyone who fits this description mustn't neglect to read, carefully and in full, the Quran, which is of course the very source of Islam, if he expects to even begin to understand the latter. And ideally, he will read it in Arabic. Maybe a particularly beautiful passage will entice:
وَهُوَ الَّذِي يُرْسِلُ الرِّيَاحَ بُشْرًا بَيْنَ يَدَيْ رَحْمَتِهِ ۖ حَتَّىٰ إِذَا أَقَلَّتْ سَحَابًا ثِقَالًا سُقْنَاهُ لِبَلَدٍ مَيِّتٍ فَأَنْزَلْنَا بِهِ الْمَاءَ فَأَخْرَجْنَا بِهِ مِنْ كُلِّ الثَّمَرَاتِ ۚ كَذَٰلِكَ نُخْرِجُ الْمَوْتَىٰ لَعَلَّكُمْ تَذَكَّرُونَ
- Surah 7.57
†'He it is who sends forth the winds between the two hands of His mercy. Once [this mercy] has gathered the clouds heavy with rain, We drive them unto a dead land, whereon causing the water to descend We make sprout all manner of vegetal life. Even so shall We raise the dead: or can it be you don't remember?'
