Joint Special Operations University has wrote a paper entitled "Building Partner Capacity", JSOU Report 15-1, February 2015. This 125-page long paper explores the sources of instability that pose security concerns to the United States and the various ways of mitigating those security concerns. It says that, in addition to humanitarian assistance and security assistance, building partner capacity is one of the best ways to diminish instability and should be a major part of the nation's grand strategy. The author provides us with the multiple ways of viewing the role of building partner capacity as part of a U.S. grand or defense strategy and the place of special operations forces in these strategies.
