Destruction of Yemeni capital does not mean that Saudi has won. It just makes a big part of the population (at least 50%) angry towards saudi arabia and will motivate them for new war. Saudi cannot accept Ansarallah as component of Yemen because that would allow Iran to enter the Yemeni market and support Yemen militarily and getting influence in red sea.
First of all Sana'a is not destroyed at all, lol. The entire world saw that already during the Houthi/allied forces military parade. So let us end this bullshit first.
Secondly Iranian influence can only be limited to smuggling of weapons. Nothing else really as KSA controls all the land borders of Yemen (Oman the other) and sea ports. Which is why Iranians are left smuggling weapons through small shipping boats, many of which have been busted by KSA and even the US NAVY that operates in the region.
Iran cannot gain any substantial influence in the Red Sea
. It is not possible logistically nor are there any pro-Iranian regime governments in power in any country that borders the Red Sea. They are all pro-KSA/under KSA-influence.
Lastly Yemenis, like all other Arabs, will never accept any foreign "overlords". Ottomans, Brits, Romans, Ethiopians, Persians and many other foreigners can confirm this.
On the other hand, Arabs inhabit/control most of the Persian Gulf. Even on the other side (Arab communities).
I don't think they would mind a small enclave there as long as the their counter-part yemenis surround them and have them in check..
These Sayidis are local and have ever been there.. No reason in committing genocide to remove them and this would be bad for them internationally..
Not really if you don't control the Bab-Al Manbaq you nobody can have any control there really nothing enters that is not sanctioned by them.. They have full control over the red sea and will be unrivaled as long as they control the Bab-Al Mandaq and the surrounding islands
Sayyids? You mean Zaydis. Zaydis are a Shia Muslim branch that is close to Sunni Islam (the closest Shia branch). The Houthis leadership claims Sayyid ancestry but many leaders in the region do that (almost).
