Would a supersonic Harrier attract earlier US support?

Would a supersonic Harrier bring the United States into the program before the Falklands War?

Not as a full early buyer, because the United States still regarded V/STOL as somewhat gimmicky, though interest and cooperation would probably increase.

The United States probably would not embrace the aircraft fully before the Falklands demonstrated Harrier combat value. A supersonic design would nevertheless draw more attention and technical cooperation. It would also require a better radar to make effective use of the additional performance. A stronger development partnership would still fall short of early American procurement.
