The most publicly discussed link between economics and security is the relationship between economic performance and power. The underpinnings for this relationship come from the philosophical approach that sees political power stemming from economic power. Espoused at least since the 17th century by English Civil War philosopher James Harrington, these ideas saw their most well known expression in the philosophy of Karl Marx, who saw economic change driving political change. If economic structures determined politics then the link with security is clear. Carl von Clausewitz’s likened war to other areas of conflict within developed societies, such as commerce and politics: “It is a conflict of great interests which is settled by bloodshed, and only in that is it different from others.”

The new defense strategy, “Sustaining U.S. Global Leadership: Priorities for 21st Century Defense,” released in January of this 2012, makes clear the mandate for the Department of Defense to continue, in fact to increase significantly, its abilities to improve the capabilities of partners around the globe. In his cover letter to the guidance, President Barack Obama directs us to “join with allies and partners around the world to build their capacity to promote security, prosperity, and human dignity.” Likewise, Secretary of Defense Leon Panetta, in his preface, stresses that the department will focus on “strengthening alliances and partnerships across all regions.”

Civilian casualties can risk the success of a combat mission. While not new, this is a lesson US defense forces have had to repeatedly relearn. Historically, civilian protection and efforts to address harm became priorities only when external pressures demanded attention. As the Pentagon reshapes its defenses and fighting force for the next decade, continuing this ad hoc pattern in the future is neither strategically smart nor ethically acceptable.
