The moment these middle eastern countries (Saudi Arabia, Qatar, Yemen) are not useful to Western foreign policy anymore and therefore lose our support, they will probably disintegrate. You've got citizens that are a minority in their own country, and that are largely incompetent and incapable of running anything, because they never had to do any work. And then you have a majority of foreign workers that are largely treated like slaves, and probably not happy with that situation. I can't see who would support those regimes if they get into troubles Europe certainly wouldn't, politicians here already call those countries dictatorships (publicly) and noone want's to have any affiliation with them. Russia and China both already had their experiences with terrorism sponsored by those regimes, so I wouldn't expect any support from them either. I think that particularly Saudi Arabia already sees the writings on the wall and they are actively taking measures but it will be too late, too little.
