MindWar is the art and science of resolving international political and military crises through the application of Psychological Control (PSYCON) techniques to the electromagnetic architecture of the human brain, replacing violent irrationality with constructive and cooperative creativity. The result is the elimination of the bloodshed of conventional physical war (PhysWar). The author's 2013 book MindWar_ introduced and detailed this methodology. We Break the Sword is one of a series of theoretical case studies of how MindWar could have been applied to various historical conflicts, in this case the European theater of World War II in 1940. It also addresses prevention of the subsequent development of atomic warfare, delaying if not eliminating that worldwide international danger. An "alternative history" of what might have come to pass - instead of the horrors that did.
