Houthi's need to regain their sanity and stop allowing themselves to be used by Iran for Iran's personal cultural hatred against Saudi's. They should reconcile with southern Yemeni's and push political transition process forward and commit to not attacking the Saudi's ever again. This will require breaking relationship with Iran. The only thing preventing peace in Yemen is Iran's role of trying to form large military front against Saudi's so they can have plausible deniability for attacks on KSA infrastructure. Iranian regime has too much hatred towards Saudi's, if they put 10% of this hatred towards Israeli's then Israeli gov't would have collapsed by now. But their heart stands where it stands ... unfortunately ....
