National Defense Strategy

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.
