You had two Ba'athist states, one in Iraq and one in Syria. Both were ruled by minorities. The Assad family came from the Alawite minority Syria and oppressed the Sunnis, while Saddam Hussein came from the Sunni minority in Iraq and oppressed the Shi'ites.
It is a matter of calculation - what today you would call game theory. If you compose a state from antagonistic elements to begin with, the rulers must come from one of the minorities. All the minorities will then feel safe, and the majority knows that there is a limit to how badly a minority can oppress a majority. That is why the Ba'ath Party regimes in Iraq and Syria - tyrannies founded on the same principle - were mirror images of each other."
"What happens if the majority rules?," I asked.
"The moment you introduce majority rule in the tribal world," the cardinal replied, "you destroy the natural equilibrium of oppression.
"The minorities have no recourse but to fight, perhaps to the death. In the case of Iraq, the presence of oil mitigates the problem.
The Shi'ites have the oil, but the Sunnis want some of the revenue, and it is easier for the Shi'ites to share the revenue than to kill the Sunnis. On the other hand, the problem is exacerbated by the presence of an aggressive neighbor who also wants the oil."
