If there is conflict between us, and I submit to your will to power, there will be peace between us. But is that a peace worth having? There is a sense in which Islam is the religion of peace, but it is more honestly described as the religion of submission.
I've added some emphases to the following quotations from Jude P. Dougherty, Fictional ISIS and the True Threat:
The word “Islam,” Goldziher reminds his reader, means “submission.” The word expresses first and foremost dependency on an unbounded Omnipotence to which man must submit and resign his will. Submission is the dominant principle inherent in all manifestations of Islam, in its ideas, forms, ethics, and worship, and it is, of course, demanded of conquered peoples. Adherence to Islam not only means an act of actual or theoretical submission to a political system but also requires the acceptance of certain articles of faith. Therein lies a difficulty.

To illustrate the difference between Christianity and Islam, Brague draws upon the work of Ibn Khaldun, a fourteenth-century Muslim scholar. According to Khaldun the Muslim community has the religious duty to convert all non-Muslims to Islam either by persuasion or by force.
Other religious groups do not have a universal mission, says Khaldun, and holy war is not a religious duty for them, save for defensive purposes. The person in charge of religious affairs in other religious groups is not concerned with power politics. Royal authority outside of Islam comes to those who have it by accident, or in some other way that has little to do with religion, and they are under the religious obligation to gain power over other nations. According to Khaldun, holy war exists only within Islam and is imposed upon its leaders by sharia law.
Theological warrant aside, Brague asks how Islam’s greatest philosophers view jihad. He puts the question to three Aristotelians – al Farabi, Avicenna, and Averroes. All three permit the waging of holy war against those who refuse Islam – al Farabi and Averroes against Christians, Avicenna against the pagans of his native Persia.
Al Farabi, who lived in the lands where the enemy was the Byzantine Empire, drew up a list of seven justifications for war, including the right to conduct war in order to acquire something the state desires, but is in the possession of another; and the right to wage holy war to force people to accept what is better for them if they do not recognize it spontaneously.
Averroes, writing in the western part of the Islamic empire, approved without reservation the slaughter of dissidents, calling for the elimination of people whose continued existence might harm the state. Avicenna similarly condones conquest and readily grants leaders the right to annihilate those called to truth, but who reject it.
Western leaders fighting ISIS [oe pretending to fight it such as the contemptible hate-America leftist, Obama] generally fail to acknowledge the genuine motivation of those committed to jihad. Whether from cowardice or woeful ignorance, they (at Europe’s peril) continue to speak of “the far reaches of ISIS,” without confronting the real threat.
