I did find this review of the book interesting. Especially his conclusion:
For those Arabs today who mourn the loss of empire and feel humiliation and inferiority at the hands of the West, they would do well to study the lessons of this book. Tolerance of other cultures and religions - not rigidity and exclusion - is the key to greatness and power.
However imperfectly we practice it, tolerance of other cultures and religions is built into the American scheme:
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.
