I stand by my statement. You know, politicians have been known to use religious arguments to further political ends. Amir Taheri's book was written in the early 1980s, when Islamic fundamentalists were in the ascendancy. This is no longer the case. Note that terrorism is a sign of weakness, not strength.
Extremism does thrive in political vacuums and in conditions of political paralysis.
When conditions change, extremists either sell out or become marginalized. It is too bad that you are so ignorant that you are unable to see that process at work. Perhaps Nostradamus's predictions do not take that into account.
