This is very valuable information, thank you.
That said, Biden should have retreated. The Saudis couldn't crush the Yemenis for years, and have no desire to fight them again. Sooner or later, some ship is going to get too close to one of those VERY moveable ballistic missile launchers, or a drone or three will get lucky, and we will see the headline US SHIP SUNK.
Of course, at a $1 million or more an anti-missile missile, there's money to be made. Ka-CHING! Raytheon doesn't care about sailors.
