That's an excellent analogy; prescient on the part of Lewis.

Prophetic, even.

My "I don't KNOW, but I THINK" file contains this notation:
The Antichrist -- not some dimestore phony, but the real deal -- will be Muslim.

Consider these concepts:
Isaac v. Ishmael and their Descendants in Confilct: Christ v. Antichrist
The Unmasking of Allah: From Allah=YHWH to Allah<>YHWH

Yes, we are not dealing with a blond haired Romanian named Nicolae Carpathia as the cult novels would suggest. In fact, St. Paul, perhaps unwittingly but under the inspiration of the Holy Spirit, did mention "another gospel" preached by an angel. Of course, Paul was using hyperbole, but it is striking in light of the claims of Islam that the Qur'an was originally given to Muhammad by the angel Gabriel.

Consider these concepts: Isaac v. Ishmael and their Descendants in Confilct: Christ v. Antichrist

The fallacy on the part of many American evangelicals is thinking that the Jews currently inhabiting Israel are the true descendants of Abraham, Isaac, and Jacob. Israel has become quite secular and atheistic these days--much like America and American Jews--such that the word "Jew" has lost a good deal of its original meaning. Notwithstanding, I do see the conflict between the God-appointed son of Abraham and the illegitimate one, and how it has played out in the divide between grace-based Christianity and works-based Islam.
