What happens when Saudi Arabia collapses? Does the royalty get the fuck out of town on their private jets with as many gold bars as they can carry?
UAE and Saudi Arabia imo will be ok. They are trying to build themselves into big entertainment and tourism hubs with their ventures into sports and investment in tourism etc I think though they will definitely suffer they may be able to weather the storm. Kuwait and Qatar on the other hand I'm not so sure about
You are forgetting the costs of running a city in the middle of a dessert.
