“I wanted people who wouldn't become too worried about casualties. One always should be concerned about casualties, but the risk of incurring casualties can't be allowed to affect decisions, unless it's evident casualties will be prohibitively heavy. There may be no safe way to write this.”

It is the inescapable duty of every decent citizen to express no interest in or enthusiasm for football and the World Cup http://www.socialaffairsunit.org.uk/blog/archives/000966.php (June 7, 2006).

Speech to the Third Army (1944)
Context: From time to time there will be some complaints that we are pushing our people too hard. I don't give a good Goddamn about such complaints. I believe in the old and sound rule that an ounce of sweat will save a gallon of blood. The harder we push, the more Germans we will kill. The more Germans we kill, the fewer of our men will be killed. Pushing means fewer casualties. I want you all to remember that.

This is often attributed to U.S. Senator Hiram Johnson, but does not appear anywhere in his speeches. Arthur Ponsonby#Falsehood in Wartime (1928) quoted: "When war is declared, Truth is the first casualty", but the first recorded use seems to be by Philip Snowden in his introduction to Truth and the War, by E. D. Morel. London, July 1916: "'Truth,' it has been said, 'is the first casualty of war.'" Samuel Johnson#The Idler (1758–1760) expressed a similar idea: "Among the calamities of war may be justly numbered the diminution of the love of truth, by the falsehoods which interest dictates and credulity encourages."
