Wiether it's fun or not for the Axis depends on their objective.
It could be, for instance, to defend Berlin AND Peenemunde AND the Rhur for three weeks (six frames, one mid-week, one weekend), at which point their atom bomb and it's delivery sytem will be deemed as developed, and the allies forced to terms.......
This may seem more of a not losing, than a win, but then it's only the obverse of the Battle of Britain.
Those Ta drivers would be the last of the few.
P-38's over Berlin the first of the many.
We DO have the planes for this (but a mosquito would be nice!)
Just saying..
