Churchill remarked to Lord Boothby: ‘Germany’s unforgivable crime before the second world war was her attempt to extricate her economic power from the world’s trading system and to create her own exchange mechanism which would deny world finance its opportunity to profit.’ The quote is from the foreword to the second edition of Sydney Rogerson’s Propaganda in the Next War. Gerard Menuhin reproduces it in his Tell the Truth and Shame the Devil, page 85 of the print edition and page 86 of the PDF.
