Turf War
If you look at the history logic would dictate that the RAF can no longer forfill the role that it was set up for under the "Smutts report" of 1917.
However times have moved on and the RAF is now the logical way to provide air power except at the tactical end of battelfield support or in close support of the fleet. I see the status quo as the best way to continue however with shrinking budgets the "lords & masters" are fighting to keep some turf and steal a little turf if they can!
