You realize the Yemeni Houthi-Ansarallah faction has been fighting Saudi Arabia and its militant proxies for a decade now, and that Saudi’s have been supplied with weaponry and operational advisers & contract personnel from US & UK (primarily experienced air force pilots and ground crews). And military outcome of all this? The Houthi-Ansarallah faction now fully control over 80% of Yemen, and are the de facto rulers and de facto military of the country. They now incorporate much of former Yemeni elite military and its stocks of Soviet era advanced weaponry (short range ballistic missiles). The Saudi backed opposition forces only control the port city of Aden & its surrounds, while the Saudi backed senior opposition politicians are permanently holed up in Saudi Arabian hotels. In short, the Houthi-Ansarallah faction has effectively won the Saudi-Yemeni war, and Saudi’s looking for an exit ramp, despite the Saudi’s being militarily backed by US & UK. Do some very basic research.
