The general theme of the Rubin book is that the Syrian government needs Israel as the other to survive. For three decades the Assad family has used the battle against the Zionist other to deflect criticism of its rule. If Israel ceased to exist it could endanger the Assad regime.
Way back I had a discussion with noted author Stephen Schwartz about some of the smaller groups in the Middle East. He pointed out that Alawites are not Muslims. In fact they are considered apostates and often persecuted historically.
The starting point for this harkens back to my posts about the Yezidis and the Cult of Angels. We often make an assumption that all the pagans converted to Islam or Christianity. This assumptionis erroneous as the Yezidi and the Iranian Yarsani live as a blended type of people with admixes of Islam, Zoroastrianism with a largely pagan religion. The authors of this also explained that this largely Kurdish group has followers in Turkey called the Alevis. The Arabic phenomena of this same Cult of Angels are the Alewites. Like Marannos they appear nominally Muslim to survive but are not.
Rubin describes the Assad rule as 1/3 mafia, 1/3 Communism and 1/3 Nazi. In reality all forms of Communist rule function like poorly run mafia operations. The real mafia has a coherent business plan. Communists live in a fantasy world where the new Socialist man replaces ethnicity. The Syrian Baath party is a local communist party with a pipe dream of Arab Nationalism added.
Like the Palestinian farce, in actuality there is no such thing as a Syrian. There are a variety of Arab groups with around 10% of the population oppressed Kurds in an illogical state. The alleged glue that holds this mix together is the Commie Pan Arabism fantasy. The notion is that Muslims, Alawites, Christians, Druze are united as Arabs against dem Jooooos. Commies forget that this pipe dream makes a great case for Israel.
While Commies rant about "greater Israel", their proxy state has been agitating for a real Greater Syria that includes Lebanon, Israel, Jordan and parts of Iraq. In fact the leader of Syria reminded Arafat (the Egyptian) "We have more authority than you do". The dirty little secret is that there is no such Saudi, Jordanian or Iraqi ethnicity either.
The Israel angle allows a corrupt non-Muslim band of impostors to govern Syria in a defacto apartheid state. While commies rail about "apartheid Israel", their pet state is a real apartheid state where an Alawite clique of 13% has a monopoly on power and runs Syria for its own personal proffit.
The more radical and anti Israel the better they appear to the far left anti-semitic Commie types and other regional states. Iran has backed this non Muslim group by pretending Alawites
are Shiites. However, this is deception as the Muslim Brotherhood did rebel and was crushed.
The same groups that cry over a single Pseudostinian death just ignored the whole episode.
Rubin's point is that a peace with Israel would endanger the survival of the Bathist corrupt Assad family and the Alewite community.
