Hamas is the occupying force in Gaza.
Both Ismail Haniyeh and Khaled Mashaal have developed reputations as billionaires while the Palestinian main base is held captive — politically intimidated, ruthlessly exploited, frequently punished — in the interest of many money-making methods.
In many ways, the middle east conflict has been institutionalized and for the once KGB developed leaderships turned into a pretty good family business.
Among the more interesting aspects of the conflict may be the language programming developed to keep the machinery working for the criminally wealthy: “The Occupation” (I call it “The Preoccupation with the Jews!”); “Resistance” (to meaningful education, health care, economic development, etc.). In all aspects, the rhetoric fed to the Palestinians is medieval and designed to serve the equivalent of feudal lords and connected families (a patronage system).
Notably, Hamas associates and backers, starting with Moscow / Moscow-Tehran, share investments in similarly feudal systems and absolute power.
