> If oil money dries up, everyone else will suffer before the IRGC. See North Korea for an example.
90% of IRGC funding comes directly from their own oil empire, without oil they barely have any funding. They can't make the other parts suffer before themselves here since they get it directly from owning the oil exports, it doesn't go via the government.
If they start trying to take money from the military then they would start the civil war themselves, they can't do that.
