Khamanei is surely laughing dragging saudi arabia and all its friends into this war. I always thought saudi arabia would be wise and accept the houthis and negotiate with them ( i even said so before that saudi arabia has no basic problem with houthis), but saudi arabia seems have no problem publicly supporting qaeda and isis now which is what they're doing in iraq and syria, so they're going full fledged salafi suicidal war.
It is too early to decide who is getting strategical advantage.
You need to wait and see how the situation will evolve.
If the KSA & Co. attack becomes bogged down in a war of attrition, then you can say that Iran got the upper hand. But in case the victory was swift and decisive, then it will KSA.
Even if the civil war drag on (which was practically the case before today) but in case KSA was able to reduce the Houthis hold on the land, then it would be a good point for them.
