It’s hard to feel bad for them but there are a lot of outcomes here which result in a lot of people dying. Pretty sure half the reason SA and friends promote violent, reactionary interpretations of Islam is to serve as a dead man’s switch in case of regime change.
Oil is basically what made the middle east a violent and reactionary place. Natural resources dominating the economy drives conflict and economic clusterfucks in all but the richest, most stable democracies (i.e. everywhere except Norway). Oil's decline in importance might be the only way to escape this cycle (even if it will probably lead to bloodshed first).
Colonialism did that, the oil was just a motivating factor.
