The publication of Dr. Wong-Diaz’s monograph coincides with the major strategic reassessment of U.S. national security interests and future military posture taking place at the national level.  The strategic environment of today requires astute statecraft to formulate and execute grand strategy--strategy that effectively blends all forms of power and uses them smartly.  Though there is no consensus on what constitutes smart use of U.S. power, the concept of “smart power” is a dominant theme in policy circles.  Smart power, however defined, is directly relevant to the SOF community. With a smaller footprint than conventional forces, SOF are both a cost effective and less visible instrument of national power.  SOF are expected to combine both hard and soft power approaches instinctively to achieve strategic level effects.  Using case studies from around the world, Dr. Wong-Diaz expertly draws the links between the strategic level projection of power by states and their consequences on the ground.
