Did Churchill Scheme for Lusitania's Sinking?

Much has been made of his part in the disaster, largely based upon his supposed desire to purposefully have the LUSITANIA sunk and so bring America into the conflict on the side of Britain.This would be achieved by the fact that American citizens regularly crossed the Atlantic on the LUSITANIA and in the event of her destruction by a U Boat ,some of them were bound to perish, thereby inflaming American opinion, resulting in America subsequently declaring war on Germany.All this sounds wonderfully sinister,especially when viewed in the light of the fact that Churchill was indeed actively seeking to embroil the U.S. with Germany,but there are a number of holes in the argument which tend to rather scupper it, (to keep it in a nautical context), as we shall see later.As first Lord of the Admiralty, Churchill was indeed fully aware of the latest intelligence updates on the positions of U-boats. These were obtained by Naval Intelligence from wireless intercepts,sighting reports and reports of sinking's.
