Rev. James V. Schall, S.J has taken the issue with ISIS head-on at Crisis Magazine.
The Islamic State and the broader jihadist movements throughout the world that agree with it are, I think, correct in their basic understanding of Islam. Plenty of evidence is found, both in the long history of early Muslim military expansion and in its theoretical interpretation of the Qur’an itself, to conclude that the Islamic State and its sympathizers have it basically right. The purpose of Islam, with the often violent means it can and does use to accomplish it, is to extend its rule, in the name of Allah, to all the world. The world cannot be at “peace” until it is all Muslim. The “terror” we see does not primarily arise from modern totalitarian theories, nationalism, or from anywhere else but what is considered, on objective evidence, to be a faithful reading of a mission assigned by Allah to the Islamic world, which has been itself largely procrastinating about fulfilling its assigned mission.
To look elsewhere for an explanation is simply not to see what the Islamic State and its friends are telling us about why they act as they do. The tendency among pragmatic Western thinkers, locked into their own narrow views, is to exclude any such motivation as an excuse of raw power. This view shows the intellectual shortcomings of Western leaders and the narrowness of much Western thought.
Jihadism, as it were, is a religious movement before it is anything else. Allah does grant violence a significant place. It is over the truth of this position, or better the inability to disprove it, that the real controversy lies. A recent essay in the American Thinker calculated that over the years of its expansion, from its beginning in the seventh and eighth centuries, some 250 million people have been killed in wars and persecutions caused by Islam. Nothing else in the history of the world, including the totalitarianisms of the last century, has been so lethal.
