I whole hearty have to disagree with you here. It's part of their religion.
"This way the Muslims have waged war on all those who lay in their path starting from the Arabs, Byzantine Christians, Egyptian Coptic Christians, Persians, Spaniards Austrians and other Europeans and many others." http://www.waronjihad.org/islam230805.html
"To give Muslims what they demand, they will demand more. If Islam cannot win what they perceive to be a war, physically, they will do so through threats of violence. ... Having taken advantage of the world and its willingness to placate, the world will ultimately become unwitting victims to the Islamic threat." http://studygrowknowblog.com/2010/07/25/islam-wants-to-rule-the-worl/
