“The Government must not insist too much on the fact that Germany will integrally fulfil the conditions of the peace treaty. For all parties have been unanimous in considering that the treaty is unfulfillable.”

Part of the statement that became known as the Ponsonby Rule (1 April 1924).
Context: It is the intention of His Majesty's Government to lay on the table of both Houses of Parliament every treaty, when signed, for a period of 21 days, after which the treaty will be ratified and published and circulated in the Treaty Series. In the case of important treaties, the Government will, of course, take an opportunity of submitting them to the House for discussion within this period. But, as the Government cannot take upon itself to decide what may be considered important or unimportant, if there is a formal demand for discussion forwarded through the usual channels from the Opposition or any other party, time will be found for the discussion of the Treaty in question.

Quotes from Michikinikwa

Published as having been made in an (August 1936) interview http://www.greatwar.nl/frames/default-churchill.html with William Griffin, editor of the New York Enquirer http://en.wikipedia.org/wiki/National_Enquirer, who was indicted for sedition http://www.time.com/time/magazine/printout/0,8816,773366,00.html by F.D.R.'s http://www.whitehouse.gov/history/presidents/fr32.html Attorney General Francis Biddle http://www.usdoj.gov/osg/aboutosg/biddlebio.htm in 1942. In a sworn statement before Congress in 1939 Griffin affirmed Churchill had said this; Congressional Record (1939-10-21), vol. 84, p. 686. In 1942, Churchill admitted having had the 1936 interview but disavowed having made the statement (The New York Times, 1942-10-22, p. 13).
In his article "The Hidden Tyranny," Benjamin Freedman attributed this quotation to an article in the isolationist http://www.time.com/time/magazine/article/0,9171,795133,00.html publication Scribner's Commentator in 1936. However, that magazine did not exist until 1939. He may have gotten the date wrong or might have been referring to one of its predecessors, Scribner's Monthly http://cdl.library.cornell.edu/moa/browse.journals/scmo.html or Payson Publishing's The Commentator http://www.time.com/time/magazine/article/0,9171,765655,00.html.
