We now have a broadly based and efficient defensive strength, including a great deterrent power, which... is, for the present, our main guarantee against war; but, unless we act wisely and promptly, we could lose that capacity to deter attack or defend ourselves.

The Navy can lose us the war, but only the Air Force can win it. Therefore our supreme effort must be to gain overwhelming mastery in the Air. In no other way at present visible can we hope to overcome the immense military power of Germany.

The great defence against aerial menace is to attack the enemy's aircraft as near as possible to their point of departure.

Air power may either end war or end civilization.

The fate of a Nation may sometimes depend upon the position of a fortress.

Nothing is more important in war than unity in command. When, therefore, you are carrying on hostilities against a single power only, you should have but one army acting on one line and led by one commander.
