Grey had perfected a manner of speaking designed to convey as little meaning as possible

From the Guns of August by Barbara Tuchman.

When the Foreign Secretary, Sir Edward Grey, telephoned him that morning, in the interval of a Cabinet meeting, Lichnowsky, out of his own anxiety, interpreted what Grey said to him as an offer by England to stay neutral and to keep France neutral in a Russo-German war, if, in return, Germany would promise not to attack France.

Actually, Grey had not said quite that. What, in his elliptical way, he offered was a promise to keep France neutral if Germany would promise to stay neutral as against France and Russia, in other words, not go to war against either, pending the result of efforts to settle the Serbian affair. After eight years as Foreign Secretary in a period of chronic “Bosnias,” as Bülow called them, Grey had perfected a manner of speaking designed to convey as little meaning as possible; his avoidance of the point-blank, said a colleague, almost amounted to method. Over the telephone, Lichnowsky, himself dazed by the coming tragedy, would have had no difficulty misunderstanding him.
