It's a proxy war - there really is little more to say. Saudi has the money to make sure it wins, and has the control, thanks to oil, to get away with doing whatever it wants. Iran is the bad guy internationally and therefore it's agenda will be seen as the 'wrong' one. Also, the west just doesn't really care about Yemen so will leave Iran and Saudi to duke it out. Unlike Ukraine, which is far more ambigious in what Putin is planning and what should be done about Russian involement, Yemen is a minor spat with both sides happily participating and little ambiguity as to the goals of each state.

Well, now what we have left is to define what're the winning conditions for the Saudis. I wouldn't be so sure, I'll wait until onland part of the operation to see how that goes before coming to any conclusions. It's immensely more complicated than Saudis vs Iran, besides I didn't see any facts of Iran involvement in Yemen so far, even though that is considered a common place. All in all I'm generally with Khan on this one (scrap the emotions) *put that pic with anthropomorphous squid exclaiming "it's a trap"* seems fitting.

As for the West, if by West you mean US, it's officially involved in the conflict, so they do care. Quote of myself:

BTW speaking about Iran...

Since you probably don't have accesss, long story short -- Hezbs have sent 20 militaty specialists to Sana to aid Houthis. Hezbollah is rather military capable organization compared to its neighbours in the region, but 20 men is surely not a decisive level of support. Probably too preocupied with Syria and Iraq affairs.

Talked about Iraq, a new offensive from IS on the way to Bagdad. At the moment only 100 KM away from Bagdad and taking over Ramadi.

So the IS airforce stopped the bombing, now they will send in the Saudi national guard to help IS take over Jemen(our to shoot every saudi soldier that runs away.)
can we pls start sanction those lunatics in Riad?

the saudis are using clusterbombs, weeeeeeeeeeeeeh, more war crimes!

Clusterbombs and phosphorus are very common these days even though prohibitted or limited by multiple conventions, but nobody cares.

So far so good. After violance has erupted in Qatif, ISIL attacked Shia mosque in the same province (how convenient, that'll surely bring "the love and friendship" between two major religious groups in Saudi Arabia to a new level). Meanwhile Houthis claimed to capture three border guard outposts on Saudi's territory, so far only one has been confirmed. Nothing major at this point, but the development looks "promising". Still no significant amount of coaltion forces on the ground even though it has been like a month since the beginning of the Restoring Hope was declared.
