A core responsibility of the U.S. Government is to protect the American people – in the words of the framers of our Constitution, to “provide for the common defense.” For more than 230 years, the U.S. Armed Forces have served as a bulwark of liberty, opportunity, and prosperity at home. Beyond our shores, America shoulders additional responsibilities on behalf of the world. For those struggling for a better life, there is and must be no stronger advocate than the United States. We remain a beacon of light for those in dark places, and for this reason we should remember that our actions and words signal the depth of our strength and resolve. For our friends and allies, as well as for our enemies and potential adversaries, our commitment to democratic values must be matched by our deeds. The spread of liberty both manifests our ideals and protects our interests.
The United States, our allies, and our partners face a spectrum of challenges, including violent transnational extremist networks, hostile states armed with weapons of mass destruction, rising regional powers, emerging space and cyber threats, natural and pandemic disasters, and a growing competition for resources. The Department of Defense must respond to these challenges while anticipating and preparing for those of tomorrow. We must balance strategic risk across our responses, making the best use of the tools at hand within the U.S. Government and among our international partners. To succeed, we must harness and integrate all aspects of national power and work closely with a wide range of allies, friends and partners. We cannot prevail if we act alone.
The President’s 2006 National Security Strategy (NSS) describes an approach founded on two pillars: promoting freedom, justice, and human dignity by working to end tyranny, promote effective democracies, and extend prosperity; and confronting the challenges of our time by leading a growing community of democracies. It seeks to foster a world of well-governed states that can meet the needs of their citizens and conduct themselves responsibly in the international system. This approach represents the best way to provide enduring security for the American people.
The National Defense Strategy (NDS) serves as the Department’s capstone document in this long-term effort. It flows from the NSS and informs the National Military Strategy. It also provides a framework for other DoD strategic guidance, specifically on campaign and contingency planning, force development, and intelligence. It reflects the results of the 2006 Quadrennial Defense Review (QDR) and lessons learned from on-going operations in Iraq, Afghanistan, and elsewhere. It addresses how the U.S. Armed Forces will fight and win America’s wars and how we seek to work with and through partner nations to shape opportunities in the international environment to enhance security and avert conflict.
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.
