So far so good, but "underpinnings of western Civilisation" took a while to fathom due to its vagueness. I guess we could be talking about East vs. West and identity of us and "the other"? "Judaic Cult Temple period" is also vague at first, but is soon put into context as the time prior to the Seleucids and then starts to sound like a nicely coined description for that period.
I take it, as I think most people do, as Judaism and Christianity form the major cultural inputs to Western civilization. These along with the Homeric corpus which fewer people realize was like a bible to the Greco-Roman world. With the latter, such as Castor and Pollux (the brothers of Helen (of Troy) were seen as salvic saviors just as Jesus would become. Castor and Pollux delivered the Apostle Paul to Rome to inaugurate Pauline (Roman) Christianity, and as I discussed in my 9/11 post, from their heavenly perch they witnessed the destruction of the twin towers.
"False dialectic" is a difficult subject - maybe a link is needed here. It's worth mentioning once that Gentile means "non-Jew". So in other words are you saying that people have been deceived into perceiving only Jews and Gentiles, but not the Oligarchs, i.e. the Rich vs. Slaves instead of Jews vs. non-Jews? But how about in the context of the Middle East and the rest of the world? "collective historical narratives"/"Western schema" have long-term time stamps attached to them, so what was the advantage of making the Jews a scape-goat during the Judaic Cult Temple Period?
False dialectic is simply a fancy term for a man-made false dichotomy, in this case employing conveniently situated peoples who have had a new culture forced upon them. Even so, as learned by the mistakes of the Amarna experiment(s) and probably similar elsewhere, it takes a very long time and significant effort to get a group of people to change their superstitious beliefs from one form to another, especially a radically different paradigm. Just look at the problems we're having today with American fundamentalists and their perception of their sacred culture being under assault.
The Temple Cult was part and parcel of the top down changes. This being a centralizing (of authority, and ease of monitoring) change from the typical Canaanite practice of having local priests and sacrifices to that of having such rituals only being allowed to take place at the centralized temple. Don't like it, go get smitten.
Cyrus H. Gordon allows that the Judaic, Ugaritic (northernmost Canaan), and Homeric epic narrative styles all shared a common source, at least. In actuality, as Robert Wright discusses in the highly recommended
The Evolution of God that the OT even includes the roots of pagan mythos in the OT that has been disguised merely by changing the names of the gods to their respective earthly mundane aspects, like geographical features (the sea, or a river, etc.)
At a minimum, the Jews are set against the goy world by the numerous cultural inversions of the so-called Mosaic Law. This really happens around the time of the Babylonian Exile period at the political behest of the Persians. They are placing their political puppets (like Nehemiah, Cyrus's cup-bearer) in charge of Canaan in a rather controversial manner, as an 'apparent' affront to a now weakened Egypt (as compared to centuries before). Here, I am guessing the ultimate motive is not much different than the modern impetus to place the Ashkenazi into Zion. Namely to create a sleight-of-hand magical diversion while other geopolitical rug pulling is taking place, and as well, as stated before, they needed some group, conveniently located to accept the seed of the new and improved religious paradigm - for more efficient social control going forward. You have to start somewhere, so do it where you can control the process the best. Then start it to spread.
In this latter regard, most people don't realize it, that unlike today, that back then Judiasm was spread by heavy proselytism, not by begetting of DNA.
What is meant by "Homeric"? I just know that Homer did some ancient Greek texts - later used in Christian typology. Are you saying that most, if not all, conflicts with the Jews were engineered by the elite? Exactly what was their purpose in terms of control through introducing an eastern mediterranean scapegoat - particularly during the earlier periods? (WWII is easy!)
We know of the battle, or battles(?) of Troy and the epic
Odysseus, among other things from Homer (or the alleged Homers?). The battle or battles might be reflections of the so-called Sea People period that plagued Egypt, and if so, this is one more reason to believe that the Judaic and Greek narratives ultimately have a common source. And that Jerry and I will continue to build our synthetic 'false dialectic' claim upon.
The easy answer to your next two questions, is yes, and the reason is simply a sophisticated 'divide and conquer' stratagem.
OK, so the new scapegoat actually represents a whole new society based on monotheism - opposite to surrounding nations. The last sentence is quite cryptic, but I think I now understand it: Yahweh jealously demands allegience only to him, offering rewards and punishments - less tolerant compared to polytheism.
First sentence is nicely put. But then "How to win friends and influence enemies" - who exactly are we talking about? Why this question? Monogamy is very nice example, but I had to look that one up like many of the words in this article!

I need 2 wives now - but I have to divorce first because I am not in a society that has my best interests at heart. Now the "attractive forms of Judaism" makes sense (for women at least). Comparison with the Romans is good - the final supplantation meaning the Christian state religion? But we are starting to lose the original thread of why the elite would want to create this.
According to the 'official story' we are asked to accept that there was an organic formulation of monotheism, either by divine inspiration, or internally within the prosaic political needs of the beleagured Judeo-Israelites. The latter is presented by Wright as an
ad hoc, piecemeal set of exigent reactions to external forces that thus accidentaly molded the Judeans in a crucible of
Perfect Storm-esque circumstances. I say that the whole process was mapped out, or rather 'gamed out' by the various priesthoods and their related nobilities.
As someone who was first raised in a mainstream Protestant denomination and then evolved radically away from that, I have always blanched at such as Biblical prophecy, such as Joe discussed with the Matthew prophecies of the End Times in CM. However, after getting into all of this and learning about how evangelicals consider the Matthew prophecies, and Daniel, and these also in terms of the Jesuit Futurist school, I now take these things as scripts and not always as retrojective faux prophecy, as most rationalists are wont to do.
As such, the formerly Canaanitic Jews cum monotheists were put on a strict 'program' or regime, for several thousand years, until the European 'emancipation' of serfs and Jews. This was clearly documented by Israel Shahak and James Carroll as I've discussed elsewhere. As such, WWII is all part of an elite control continuum.
I included the phrase: "How to win friends and influence enemies", to point out the oddity of purposely establishing oneself onto a pedestal as an apparent elite, for everyone else to take a pot shot at. How nice to convince yourself that you are doing so so as to attract seemingly eternal enmity - for the sake of those who you've made hate you by your widely divergent practices. In the process, fortunately, most everyone did get a relative upgrade on certain moral practices while all the Atonement was going on. But also, those freed serfs convinced themselves that they were the new Chosen and thus were biblically justified in enslaving (and worse) the New World.
