So basically, the US is now aligned with Al-Qa`idah in two places: Syria and Yemen

"Local militias backed by Saudi Arabia, special forces from the United Arab Emirates and al Qaeda militants all fought on the same side this week to wrest back control over most of Yemen’s second city, Aden, from pro-Iranian Houthi rebels, according to local residents and Houthi forces." "Meanwhile, Saudi-backed militias are spearheading efforts to roll back Houthi gains and reinstate the government that the rebels drove into exile in neighboring Saudi Arabia. But they have turned to Yemen-based al Qaeda in the Arabian Peninsula, or AQAP, for help, according to local residents and a senior Western diplomat. This puts the U.S.-allied Gulf kingdom on the same side as one of the world’s most notorious extremist groups."
