Covered most of your points earlier in this thread and many others. Prefer not to repeat myself but allow me to disagree with some of your points.
Anyway what is the "Arab cause" exactly? Palestine is a small part of this.
You are too obsessed about KSA, nowhere has "Saudi Arabian policy" enabled Israel anywhere. KSA has been championing the Palestinian cause since 1948 (unlike Iran) and to this day politically it was KSA and France that was behind major Western European countries (for the first time) recognizing Palestine (UK, France etc. itself). The most pro-Palestinian concrete change in the past 2 years.
France, Andorra, Belgium, Luxembourg, Malta, Monaco join diplomatic push as Israel unleashes fierce attacks on Gaza.

Due to mostly Saudi Arabian lobbying.
Anyway fine, let us assume your logic is correct.
What has "Iran championing" Palestine amounted to or given the Palestinians if not utter humiliation, defeat and the worst loss of live in the entire conflict?
If we go by your logic, the whole Iranian agenda has failed miserably. Hezbollah destroyed/South Lebanon, Gaza leveled to the ground etc. Some even say that 7th of October was coordinated with Iran in order to stop more Arab states normalizing with Israel and trying to find a diplomatic solution by engaging with Israel/Israelis for the first time in history directly and opening up more people to people relations in order (partially) also to help sway Israeli opinions in more pro-Arab directions. We don't really know what could/would have occurred long-term. Some pragmatics could easily say that it would be worth a try given that the alternatives (hostility, no ties at all) did not work or change status quo, rather the contrary, more settlements were being built each year.
The Houthi vs Yemen/KSA/Arab coalition war ended in 2020 by large. You were off by half (decade claim).
The backward Houthis are just opportunists, using the conflict for their own gains while achieving nothing (yet to kill more than 1 Israeli). If that is victory in your world, so be it. In return Israel has killed 100's of Yemenis.
Just cheap useless rhetoric that does not amount to anything. The military solution is not going to work against a nuclear armed Israel fully backed by the US/West/NATO. Even Russia supports it and China has excellent ties with it. This delusion will just continue to kill more Palestinians and people of the region.
I am happy that KSA is not engaging in this low IQ rhetoric/politics but tries to first unify Palestinian ranks (KSA brokered the Hamas/Fatah civil war), offer a concrete realistic peace proposal (Arab Peace Initiative) and is lobbying heavily for a Palestinian state which amounted to major Western European states officially recognizing a Palestinian state for the first time.
Anyway KSA/Arabs/Muslims/outsiders can only do so much, at the end of the day Palestinians and Israelis (in particular the Israelis) need to figure out a peaceful coexistence/just end to the conflict/solution and the most important outsider here is the US who holds the most sway over Israel.
BTW, some of your points would have more value if Iranian regime and Iran-aligned groups actually had amounted to something in regard to defeating Israel. Not the case which the entire world has already seen. Nor were you capable of preventing the genocide in Gaza (nobody was). My point is, the military solution has been tried (long before that) and has largely (not largely, failed completely) since 1948. Unlikely to change. Call me defeatist or whatever (don't really care) but I am pragmatic and focused on facts on the ground rather than wishful thinking or empty slogans.
And if it was so easy to solve this conflict, it would not have lasted so long and somebody would have solved it by now some way or another by forcing the hand of both, in particular Israel.
And no, personally I am not in favor of having any kind of relations with Israel (the state) but my opinion does not matter (yours neither) in this region and for the leaderships of this region. Nor do we know if "normalization"/genuine people to people interactions and trying the diplomatic solution (seriously) long-term will/would have any effects as that has never been tried before by the region collectively with outside support from relevant powers.
What I do know is that everyone in the region is tired of this conflict, including those involved directly (naturally) and that we want to see an end to this madness once and for all in one form or another that can realistically satisfy both parties because neither of them are going anywhere. The region has been hijacked long enough already by this nonsense, largely (99.99%) the fault of Israel/Jews. No sane person wants any wars or conflicts in the first place with anybody but wants to have peace, stability and development. I don't want for my sons and children to grow up in a region that Is permanently at war or in a region where the next war/conflict is just a question of time.
