Religion of Peace or Ideology of War?

Spengler, in the Asia Times, has an interesting article on Islam. His assertion is that unlike Christianity and Judaism, Islam is both a religion and a political ideology. And that "[r]eligion is what makes Islamic political ideology so dangerous."

Religion offers the individual a way of transcending death by separating the holy, or eternal, from the profane, or transitory. It presupposes not merely an eternal plane of being exalted above mere creation, but also some means by which mortals may participate in this higher being through revelation and grace, and some procedure by which they may obtain grace, that is, ritual and prayer.

In Islam, this procedure is jihad.

I'm not sure that I completely agree with this characterization of Islam. I would say that Islam is the religion, while Islamism is the political ideology. Unlike the other two major religions, Islam has never had a "reformation", and because of this it seeks to control both the religious sphere of life, as well as the secular.
