Captain Dean T. Olson, author of Perfect Enemy: The Law Enforcement Manual of Islamist Terrorism, told FrontPage that the primary reason for the acceleration of Islamic radicalization is that the West has failed to wage an ideological offensive, particularly against the propaganda that is successfully teaching Muslims that the U.S. is waging a war against Islam, a theme pushed by Muslim Brotherhood affiliates in the West.
"This ideology is espoused in the U.S. by the 80 percent of mosques controlled by the Saudi Wahhabis and increasingly by the explosive growth of media and the Internet as tools to recruit jihadists," he said. One FBI counter-terrorism official estimated that roughly 10 percent of imams at the roughly 2,000 mosques in the U.S. preach extremism, but conceded it was a conservative estimate.
Polls of Muslim-Americans show a mixed picture. Interestingly, a Pew survey in 2007 found that "Native-born Muslims express overwhelming support for the notion that mosques should express their views on social and political matters. By contrast, a large majority of foreign-born Muslims—many of whom are from countries where religion and politics are often closely intertwined—say that mosques should keep out of political matters." A total of 49 percent of Muslims in the U.S. want their mosques to stay out of political issues. It appears that the Muslims who have first-hand experience with the combination of mosque and state are most likely to oppose it.
