Not Churchill, re Germany: “We butchered the wrong pig”
Digital scans of 80 million words by and about Churchill, including his books, articles, speeches and published papers, offer no instance of this phrase, either with the word “slaughtered” or the word “butchered.” Neither did I find any statement of his suggesting Britain had “fought the wrong enemy.” One of Churchill's virtues was to recognize the main threat to peace at each juncture in his career. From 1933 to 1945, he was certain that Nazi Germany was not the "wrong pig." He did begin to think, late in the war, that one mortal foe had given rise to another. But he always kept things in perspective.
