The Houthi claimed responsibility, for starters. Also, as noted by Scott Ritter, 'there is the largest concentration of modern air defense radars in the Persian Gulf oriented toward Iran, and not one detected and tracked these launches?' The Iran connection was immediately seized by both the USG and SA for their own purposes before the incident was even investigated. Both sides have motives that encourage fingering Iran. They promised to reveal the findings, but as of today, nothing further has been made public. This, despite the fact that the USG should have readily available sensor data that would show if the attack were to have originated in Iran, and if it were so, then that would be a causus belli for direct war on Iran, yet that dog never barked.
