But to the fanatics behind the Tube bombings, taking power in a major Western European state is just part of their holy jihad against the West.

At the root of the Islamic philosophy of Osama bin Laden and his followers is the belief that America and its allies, such as Britain, are occupying Muslim lands and waging a modern-day Christian crusade against Islam.
Osama bin Laden wants to turn the historical clock back to the 13th century when the Islamic empire of the Ottomans stretched from the deserts of China to Spain and to the gates of Vienna in Austria. These fanatics believe that the presence of US and British troops in Iraq and Saudi Arabia is just part of the United States' plan to dominate the world and control the world's oil supplies.
If they won their war of terror, bin Laden would take control of the oil wealth of Saudi Arabia, expel all American troops from Iraq and wipe the Jewish state of Israel off the map. They want Islam, not the United States, to rule the world and they are prepared to use any means - terrorism, hijacking and suicide bombing - to further their aim."
