Department of Defense, 2008 National Defense Strategy: “The NDS describes our overarching goals and strategy. It outlines how DoD will support the objectives outlined in the NSS, including the need to strengthen alliances and build new partnerships to defeat global terrorism and prevent attacks against us, our allies, and our friends; prevent our enemies from threatening us, our allies, and our friends with weapons of mass destruction (WMD); work with others to defuse regional conflicts, including conflict intervention; and transform national security institutions to face the challenges of the 21st century. The NDS acts on these objectives, evaluates the strategic environment, challenges, and risks we must consider in achieving them, and maps the way forward.”
