“New discord has arisen in Europe of late years from the fact that Germany is not satisfied with the result of the late War. I have indicated several times that Germany got off lightly after the Great War. I know that that is not always a fashionable opinion, but the facts repudiate the idea that a Carthaginian peace was in fact imposed upon Germany. No division was made of the great masses of the German people. No portion of Germany inhabited by Germans was detached, except where there was the difficulty of disentangling the population of the Silesian border. No attempt was made to divide Germany as between the northern and southern portions which might well have tempted the conquerors at that time. No State was carved out of Germany. She underwent no serious territorial loss, except the loss of Alsace and Lorraine, which she herself had seized only 50 years before. The great mass of the Germans remained united after all that Europe had passed through, and they are more vehemently united to-day than ever before. You may talk of the War indemnity; what has happened there? I suppose that the Germans paid, in round terms, £1,000,000,000. But they had borrowed £2,000,000,000 at the same time, and there are no signs of their paying back.”

Declaration of War Broadcast, on the outbreak of the Second World War, 3 September 1939
First Term as Prime Minister (1939-1941)
Context: Fellow Australians, it is my melancholy duty to inform you officially that, in consequence of the persistence of Germany in her invasion of Poland, Great Britain has declared war upon her, and that, as a result, Australia is also at war. No harder task can fall to the lot of a democratic leader than to make such an announcement. Great Britain and France, with the cooperation of the British Dominions, have struggled to avoid this tragedy. They have, as I firmly believe, been patient; they have kept the door of negotiation open; they have given no cause for aggression. But in the result their efforts have failed and we are, therefore, as a great family of nations, involved in a struggle which we must at all costs win, and which we believe in our hearts we will win...
