A new anti-US hub, which is emerging, is the Muslim diaspora in West Europe, consisting of Muslims who had migrated to different countries of West Europe from the countries of the Islamic world. Osama bin Laden and his ideology have a growing following in this diaspora - particularly among Muslims of Moroccan and Pakistani origin, who constitute the largest number of terrorist suspects detained for questioning in connection with the investigation of different terrorist incidents. The countries needing a special watch are the UK, Spain and France. It is my assessment that there is likely to be another attempt for a 9/11-like terrorist strike in the US homeland in retaliation for the alleged desecration of the Holy Koran. Saudi, Moroccan and Pakistani nationals or foreign nationals of Saudi, Moroccan and Pakistani origin are likely to play the leadership, as well as the foot-jihadi roles in the efforts to plan, mount and execute another catastrophic terrorist strike in the US homeland. Saudis are in the forefront of the current terrorist wave in Iraq and Pakistanis in Afghanistan. Moroccans played a central role in the terrorist strikes in Madrid last year.

While the devices used for triggering off an explosion are becoming more and more sophisticated, the explosives actually used are more and more commonplace.The use of sophisticated explosives such as Semtex, RDX etc has given place to more commonplace ones such as nitrogenous fertilizers, whose acquisition is unlikely to give rise to suspicion. It is only a question of time before the terrorists start using the fuel contained in the tank of any automobile as an explosive and incendiary device for causing casualties and material damage. All they need to do is to devise a mechanism by which a suicide terrorist can cause an explosion in his fuel tank while at the steering wheel of his vehicle. If they manage to do so, prevention can become an impossibility.
