Pipes defines an Islamist as one who believes Islam is the solution to every problem. "In America, an Islamist would be somebody who wants to replace the constitution with the Qur’an.2 It is a totalitarian movement that has much in common with fascism and Marxism-Leninism." He estimates that about 10-15 percent of Muslims in the world are Islamists, which is tantamount to well over a hundred million people. Pipes adds that the percentage is probably in the same order of magnitude among U.S. Muslims. He forecasts: "There will be more attacks by Islamists on Americans. I can say this confidently because so many signs point in this direction. These assaults will awaken people. I expect it to be a one-way process of what I call education by murder. I do expect ever more Americans to worry; contrarily, I do not expect to hear many say, ’Well, I used to be worried about the threat of militant Islam, but no longer.’ As time passes and more events occur, their assessment will become more realistic...’extremists’ have ’taken over 80 percent of the mosques’ in the United States..."The Muslim population in this country is not like any other group, for it includes within it a substantial body of people - many times more numerous than the agents of Osama bin Laden - who share with the suicide hijackers a hatred of the United States and the desire, ultimately, to transform it into a nation living under the strictures of militant Islam.
