Seeker, i will follow you in this digression.

I think the LW lost the airwar, especially in the west through the inflexibility of the high command (especially Goering and Hitler himself).
The LW command didnt see the neccessity to produce masses of fighters for the defense before the early 1944. Before that any plane that was planned for production, must have had the ability to carry bombs.
This stupidy lead i.e. to a 6 month delay in ME262 production start, cause it was not cleared for mass production till it could be used as a fighter-bomber!
The problem was - as you mentioned- that the German Army in general treated the LW more as an assistance to the ground forces, especially the tanks. And when the LW was confronted with a defensive situation the command wasn't able to switch contexts.
The LW didnt really have the equitment for a defensive war till mid 1944 and than this equitment could not bring in its performance, cause the pilots that could fly it were dead or badly inexperienced.
I believe that the only defensive action won during the war by the LW were the engagement over france with the RAF in 1941 and 1942. Those were credited mainly to A. Gallands ability to switch tactics and adoped new ways of fighting.
In all larger defensive actions the LW lost, cause the whole command staff was still thinking "offensive" and could not react to the "new way" of war they had to fight.
On the other hand the fins concentrated on the defense and they acted according to this tactical doctrine. But even they couldnt stand the numbers and had to accept a peace dictate in 1944.
