The obsessive ethnocentrism of the Jews has meant that they could never acquire the strength of numbers required for the kind of great undertakings that require a large population, military ventures being the most obvious example. For that reason, Jews have been forced to develop ideologies that recruit other people to their cause, inveigling non-Jews into pursuing a Jewish ethnic agenda through a process of intellectual or emotional capture. The two most destructive examples of this, so far, have been Islam and Communism.
A few days ago I wrote (link) about the book Hagarism, which describes how the Jews created Islam to recruit an Arab army to aid them in the reconquest of Palestine, having been forced to flee it after a betrayal too far.
In the tradition of Jewish Biblical interpretation, Muslims are identified with the figure of Ishmael in the Book of Genesis. The Islamic tradition, too, recognises Ishmael as the Ur-ancestor of the Arabs. The Genesis episode curiously prefigures exactly the phenomenon I have described above. In the biblical narrative, Abraham's wife, Sarah, is unable to bear him children. She suggests to Abraham that he impregnate their Egyptian slave/servant girl, whose name is Hagar, instead. This he does, and she gives birth to Ishmael. Later, she is sent away.
Here we see a microcosmic representation of the basic relationship between Jews and Muslims. Just as Abraham cannot (as he then believes) gain a son, Jews cannot gain sufficient numbers on their own. They recruit the prototypical Muslimah, the Egyptian slave, to make up the deficit. And her son, Ishmael, symbolic progenitor of Muslims, shall be "a wild man; his hand will be against every man, and every man's hand against him". The world has been living with the consequences to this day.
Here is the relevant passage from the Book of Genesis.
