Despite being disparaged as the refuge of the weak and pernicious, the chosen mode of Asiatic and other duplicitous peoples, ever since antiquity deceptive measures have enabled dramatic battlefield success by acting as a "lever or power." Historical records unequivocally show both China and the West have virtually unbroken traditions of innovating deceit and employing deception. Western tacticians theorized less, but they well recognized the advantages of deceit, maneuver, betrayal, and false treaties. Lever of Power comprehensively examines deception's historical evolution in China and the West; provides extensive translations of important Chinese, Greek, and Latin military writings on the concept; and characterizes the chief measures in terms of method, dynamics, and objective. Numerous important, commonly recognized historical exemplifications - many still assiduously studied in PRC think tanks -- are provided for each category, resulting in a fundamental study of deception that synthesizes theory and illustrative case studies.
