I am not an aeronautical engineer, just Electrical.
But my father was a pilot, my uncle and instructor, and I was flying a plane (no, not taking off or landing) before I could drive a car.
No way a plane with no vertical stabilzer could jig & jag with modern fighters without one (or two). Even with thrust-vectoring. As most modern fighters have that as well.
IMHO.
I just saw this video & thought I would share:
