"Many prominent Muslim clerics hold the view that mosques are more than just places of worship, and that using them for military purposes as part of jihad is legitimate." - March 1, 2009, Intelligence and Terrorism Information Center at the Israel Intelligence Heritage & Commemoration Center
Readers of NEWSRAEL will know that many of the important MEMRI videos we have posted show Imam or other clerics in the West with message of war, conquest, hatred of the "Infidels" and promise of taking over the Western countries they live in. These "sermons" usually end in Arabic prayers calling for the annihilation of Jews, Christians and anyone who doesn't accept Islam.
These clerics will tell you in one paragraph that the Jews are trying to take over the world (BAD), and then tell their "flock" that Allah promised that Islam would rule the world (GREAT).
To the local people who pass by a mosque - they see a place for prayer, just like their church or synagogue.
