As YG has noted, there are plenty of rousing Italian military phrases available for the WWII period if we go by Mussolini alone (I once read an amusing one-liner that said “If slogans could win a war by themselves, Italy will be a world power”), but apparently not much if we look in the direction of generals and admirals. One compromise solution might be to quote General Giulio Douhet, one of his era’s greatest experts on aerial warfare in general and strategic bombing in particular. I’ve copied below various quotes from him; I particularly like the first one, which sounds like something Clausewitz might have said. From the point of view of YG’s project requirements, however, there’s the potential problem that Douhet was mainly a theorist and that he died in 1930. On the other hand, if nothing better can be found, he might do.
Victory smiles upon those who anticipate the change in the character of war, not upon those who wait to adapt themselves after the changes occur.
To conquer the command of the air means victory; to be beaten in the air means defeat and acceptance of whatever terms the enemy may be pleased to impose.
The one effective method of defending one’s own territory from an offensive by air is to destroy the enemy’s air power with the greatest possible speed.
Тhe battlefield in the air will be the decisive one
Because of its independence of surface limitations and its superior speed the airplane is the offensive weapon par excellence.
