I don’t really care about arab affairs but I’ve always wondered why rich nations like KSA and UAE never helped yemen get out of 3rd world status

not saying they have to but you’d assume that they’d feel bad about Yemen’s dire state and help Yemen develop with all the wealth that they have
The khaleeji Arabs do not care about the Muslim ummah sxb u have to understand that. As for the war, I am against Saudi Arabia (I am pro turkey/Qatar) but you have to understand the war is a proxy conflict between Iran vs Saudi not Saudi vs Yemen. The Saudis were forced to intervene as a result of the houthi rebellion backed by the shia. It would have been a serious problem for a pro-Shia Yemeni state bordering some majority Shia-areas in Saudi Arabia as the Iranian would undoubtedly use their influence in Yemen to topple the Saudi monarchy.
Furthermore, the Houthis follow a branch of zaidi Shia islam which very divergent from the Shia doctrine followed by the Iranians. It is the closest Shia branch to Sunni Islam. I imagine the Iranians planned to gradually convert the zaidis to the mainstream shiaism practiced by iranians iraqis etc
I would blame Iran as well I’m sure they knew Saudi Arabia would intervene as a result of their actions.
At the end of the day, Turkey is the only muslim power with a backbone atm
