A curse on all their houses is the old saying. The Houthis may light a few fires at oil refineries but they lack the power to seriously threaten the Saudi regime.
Vast areas of Yemen are now controlled by Al Qaeda. There is not a lot which separates the philosophy of Saudi's Salafi oriented militias and Al Qaeda's philosophy. Overlay that with the fighting between Saudi backed militias and UAE backed militias over the past few months and the long term risk to the House of Saud becomes clearer.
I've always been of the view that the Saudi's have created their own Trojan horse in Yemen. Decades long Iranian influence over the Houthis is seen as the key threat. However as Saudi Arabia is predominantly Salafi/Wahid/Sunni and neither nor its Houthi proxies can change that.
