As a civilization and a religion, Islam envisions the optimal world order very differently – as a caliphate, in which faith and government are united and peace prevails throughout the Dar al-Islam, or house of Islam. That is certainly not the belief of all Muslims or of the governments of Muslim-majority states, but the radicalism espoused by groups like the Islamic State seeks to spread not just codes of conduct but an entire worldview.
身负文明和宗教双重角色的伊斯兰教所认为的世界最优秩序截然不同——他们认为应当建立政教合一的（哈里发）国家，让整个伊斯兰地区共享和平。这无疑并非所有穆斯林或主要穆斯林政府的看法，但“伊斯兰国”等组织信奉的激进主义目的不仅限于传播一种行为规范，而是全套世界观的推行。
