There are few weapons that can be described as a panacea solution but it should not stop us procuring one that gives us a more competitive edge than the opposition in any particular scenario. The days of "You'll never get clearance for a BVR shot" are over. The quality and quantity of data and the real time dissemination to the sharp end now permits the use of weapons that will ruin a good fighter pilots day before he knows what day it is.
Sadly, experience, skill and cunning are now less important than technology.
