Abstract
Harry S. Truman's speaking on the subject of Soviet‐American relations from the inception of his presidency on April 12, 1945 until the enunciation of the Truman Doctrine on March 12, 1947, failed at one of the central tasks of the rhetorical presidency: atmospheric definition and regulation. To understand the reasons for this failure, one must explore both the philosophical and psychological factors underlying Truman's reticence to speak out on the deteriorating state of U.S.‐U.S.S.R. relations.
