I want to know the answer to the following question:
In the 1920's and 30's to theorist thought wars could be won by air forces what were their names?
All the background I'm provided with is that "In the 1920s and 1930s, air power theorists Giulio Douhet and Billy Mitchell espoused the idea that air forces could win wars by themselves, without a need for land and sea fighting.". Is that enough to answer the question?
Answer: yes
