The 2007 documentary Undercover Mosque speaks about the threat of Wahabi Islam.

Now this is an old documentary from 2007 but it is relevant today. Basically it's about how some reporters went undercover and found out many Muslim Clerics especially so called "Moderate" ones, have ties to Saudi Arabia and espoused the Wahabi Version of Islam under the noses of the British government. In the video many of them openly called for violence against the UK and its citizens and advocated for the takeover of the UK.





Note: I specifically said Wahabi Islam because not all versions of Islam tolerate terrorism.
