Let us calculate the speed of incoming missile, air craft speed, angel, NEZ of hostile BVR, the angle needed to avoid that, any risk of stall after applying TVC, how much it will have the power to avoid the stall and so to push the bird to negate incoming BVR?
By your post I see that all the aircrafts without TVC in the world are now obsolete and redundant/sitting ducks since they don't have TVC against BVR.
In my humble opinion & limited knowledge; we have totally misunderstood/misreading the need of TVC, its operational benefits, pros & cons and above all the intended purpose.
Not the first time though.
