You could make the argument that it makes sense to side with the Saudis, for now, due to Iran’s ongoing development of nuclear weapons and delivery systems, which must be stopped. And there is the fact that the new KSA Crown Prince, Mohammad bin Salman, seems to be taking action to reign in the Wahabi factions.
That said, long term they are still our enemies.
Actually, long term, SaudiArabia is a staunch ally.
Ditto the GCC
....”long term they are still our enemies”....
Not exactly so...”long term” the US has had ‘decades’ of friendship with the Sauds..though bumpy at times.
