“Pentagon says”! Man, you’re better than that. Yes, the Ukes can be trained to drive, load and press the button. Are they using Ukrainian F-35s or just Uke pilots flying US jets. Do you really think the Russians are stupid enough to believe “Pentagon says” too? It’s kinda depressing to see just how powerful the media is.
You're crazily fixated on f-35s. Its only one way of many to get gps coordinates to HIMARS. Others are satellite intel, drones, counterbattery radars, targets can be geolocated using pictures, old fashioned way with people on the ground using maps, etc.
