As war against a murderous Stalinist tyranny rages in Iraq, these two books address the big picture of the West's (meaning America's) relations with Islam, or rather with the Arab world, since neither author has much to say about Bosnia, India or South-East Asia, or indeed about Europe. Princeton's Bernard Lewis has the not inconsiderable advantage of knowing the languages and history of the Islamic world, whereas the LSE's John Gray expatiates on an enormous range of more-or-less related themes despite his competence in any single field (such as economics, history, the Middle East, religion, terrorism) being unclear.
