Unity of command is essential to the economy of time. Warfare in the field was like a siege: by directing all one's force to a single point a breach might be made, and the equilibrium of opposition destroyed.
There's in people simply an urge to destroy, an urge to kill, to murder and rage, and until all mankind, without exception, undergoes a great change, wars will be waged, everything that has been built up, cultivated, and grown will be destroyed and disfigured, after which mankind will have to begin all over again
May it not also be that the cause of civilization itself will be defended by the skill and devotion of a few thousand airmen? There never has been, I suppose, in all the world, in all the history of war, such an opportunity for youth. The Knights of the Round Table, the Crusaders, all fall back into the past.
