"There is a historical precedent in the spread of Islam itself, in the 7th century ... In fact, the Arabs didn't outright conquer Palestine, Syria, Anatolia, Egypt, North Africa, Iraq, and the Iranian plateau. They struck alliances with the local rebels: the Copts and the Syriacs, the Nestorians and the Donatists, the Jews and the Mardakites, with those who spoke neither Greek nor Persian and shared neither the beliefs of the basileus nor those of the shah. Even the green flag of Islam was borrowed from non-Arabs: It was originally the symbol of rebellion in Byzantium, the equivalent in its day of the red flag in ours. Can history repeat itself, and fundamentalist Islam subdue Europe in the 21st century with the help of European extremists? Will the green flag and the red flag wave side by side? Buses are burning in France and nobody, so far, seems to know how to stop that."
