Well we just spent billions buying an air defence fighter for the RAF, even though the RAF have never shot down another aircraft in A2A combat since WW2, and is never likely to ever again in any seriously probable conflict scenario. So you could say that most of the RAF is spent supporting the careers of the senior RAF officers who came to that decision.
You're not even trying anymore (though you are very trying).
Anyone want to poke a few holes in that tripe?
