I want to know the answer to the following question:
What was the major cause of the separation between the Luftwaffe and the other military structure?
All the background I'm provided with is that "In July 1939, Göring arranged a display of the Luftwaffe's most advanced equipment at Rechlin, to give the impression the air force was more prepared for a strategic air war than was actually the case.". Is that enough to answer the question?
Answer: no
