Saudi has been in a cold war with Iran for decades because it wants to be a regional hegemon and hasn’t been quiet about it. Turkey is more circumspect, giving everybody face while cutting them off at the knees in the shadows. Egypt, by comparison, would much prefer to stay out of everybody’s business and have them stay out of theirs. They’ve got more interests in Sudan and Ethiopia at this point.
The really crazy part about this war is it’s the same pastoralist vs agriculturalist conflict we’ve been having as a species since the neolithic.
