Ok.

What gives?

Either this thing is top secret and has capabilities that will stun and amaze and it should be KEPT secret or its just another fighter and we should sell it to every Tom, Dick and Harry on the planet.

Spectacles like this don't encourage the "game changer" mantra that many spout though.

The UAE has already been told they can't buy it.  Has that changed?  If it has then what does that mean?
