There is an Islamic terrorism based on socio-religious perceptions. It may not include the whole Arab and Muslim world, but it perceives the terrorism it wages against the West as an integral part of its religion. The West in general and the USA in particular cannot ignore it and should therefore unite their efforts in an attempt to find different means of countering this kind of Islamic terrorism.
The West should learn from one of the best students of Islamic fundamentalism and radicalism, the Dutch scholar, Prof. Johannes Jansen:
In a fiercely competitive society the dominant religion may preach that the greatest virtue is to love ones neighbor. The religion of a group which over the centuries has become marginalised may, on the other hand, preach that God has exclusively and explicitly chosen those who follow his commandments. This group may come to believe that it plays a central role in the history of God and his creation. In a society where the law is not much more than an interesting but highly theoretical matter, the major religion may proclaim that following Gods laws is the only way to put things right. . . Islamic fundamentalism is both politics and religion. It has a dual nature. When it is analyzed as if it were a movement that has political nature only, mistakes are made because fundamentalism is fully religion at the same time. 
In the Islamic world one cannot differentiate between the political violence of Islamic groups and their popular support derived from religion. They, at any rate, do not recognize any disparity.
The important question remains as to how the West should defend itself against Islamic terrorism. To address the question would require another article. Suffice it to say that in order to deal with this problem, the West must first recognize that the present terrorism on the part of the Arab and Muslim world is Islamic in nature.
