For a movement to be a serious threat to the imperialist West, it must be coherent and united, which is simply not the case of what is termed "Radical Islam." A united, militant Islamic world would indeed be a serious threat to the West, but nothing like that is in the offing, with the result that “Political Islam,” divided, remains weak and ineffectual. So much for the Clash of Civilizations theories, based on ideology rather than concrete history.
