Quotes from Giulio Douhet

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.

Because of its independence of surface limitations and its superior speed the airplane is the offensive weapon par excellence.

Would not the sight of a single enemy airplane be enough to induce a formidable panic? Normal life would be unable to continue under the constant threat of death and imminent destruction.

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.

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.

In order to assure an adequate national defense, it is necessary - and sufficient - to be in a position in case of war to conquer the command of the air.
