Sustaining U.S. Global Leadership: Priorities for 21st Century Defense 1

Introduction
The United States has played a leading role in transforming the international system over the
past sixty-five years. Working with like-minded nations, the United States has created a
safer, more stable, and more prosperous world for the American people, our allies, and our
partners around the globe than existed prior to World War II. Over the last decade, we have
undertaken extended operations in Iraq and Afghanistan to bring stability to those countries
and secure our interests. As we responsibly draw down from these two operations, take
steps to protect our nation’s economic vitality, and protect our interests in a world of
accelerating change, we face an inflection point. This merited an assessment of the U.S.
defense strategy in light of the changing geopolitical environment and our changing fiscal
circumstances. This assessment reflects the President’s strategic direction to the Department
and was deeply informed by the Department’s civilian and military leadership, including the
Joint Chiefs of Staff, the Secretaries of the Military Departments, and the Combatant
Commanders. Out of the assessment we developed a defense strategy that transitions our
Defense enterprise from an emphasis on today’s wars to preparing for future challenges,
protects the broad range of U.S. national security interests, advances the Department’s
efforts to rebalance and reform, and supports the national security imperative of deficit
reduction through a lower level of defense spending.
This strategic guidance document describes the projected security environment and the key
military missions for which the Department of Defense (DoD) will prepare. It is intended as
a blueprint for the Joint Force in 2020, providing a set of precepts that will help guide
decisions regarding the size and shape of the force over subsequent program and budget
cycles, and highlighting some of the strategic risks that may be associated with the proposed
strategy.
A Challenging Global Security Environment
The global security environment presents an increasingly complex set of challenges and
opportunities to which all elements of U.S. national power must be applied.
The demise of Osama bin Laden and the capturing or killing of many other senior al-Qa’ida
leaders have rendered the group far less capable. However, al-Qa’ida and its affiliates
remain active in Pakistan, Afghanistan, Yemen, Somalia, and elsewhere. More broadly,
violent extremists will continue to threaten U.S. interests, allies, partners, and the homeland.
The primary loci of these threats are South Asia and the Middle East. With the diffusion of
destructive technology, these extremists have the potential to pose catastrophic threats that
could directly affect our security and prosperity. For the foreseeable future, the United
States will continue to take an active approach to countering these threats by monitoring the
activities of non-state threats worldwide, working with allies and partners to establish
control over ungoverned territories, and directly striking the most dangerous groups and
individuals when necessary.

U.S. economic and security interests are inextricably linked to developments in the arc
extending from the Western Pacific and East Asia into the Indian Ocean region and South
Asia, creating a mix of evolving challenges and opportunities. Accordingly, while the U.S.
military will continue to contribute to security globally, we will of necessity rebalance
toward the Asia-Pacific region. Our relationships with Asian allies and key partners are
critical to the future stability and growth of the region. We will emphasize our existing
alliances, which provide a vital foundation for Asia-Pacific security. We will also expand
our networks of cooperation with emerging partners throughout the Asia-Pacific to ensure
collective capability and capacity for securing common interests. The United States is also
investing in a long-term strategic partnership with India to support its ability to serve as a
regional economic anchor and provider of security in the broader Indian Ocean region.
Furthermore, we will maintain peace on the Korean Peninsula by effectively working with
allies and other regional states to deter and defend against provocation from North Korea,
which is actively pursuing a nuclear weapons program.
The maintenance of peace, stability, the free flow of commerce, and of U.S. influence in this
dynamic region will depend in part on an underlying balance of military capability and
presence. Over the long term, China’s emergence as a regional power will have the
potential to affect the U.S. economy and our security in a variety of ways. Our two
countries have a strong stake in peace and stability in East Asia and an interest in building a
cooperative bilateral relationship. However, the growth of China’s military power must be
accompanied by greater clarity of its strategic intentions in order to avoid causing friction in
the region. The United States will continue to make the necessary investments to ensure that
we maintain regional access and the ability to operate freely in keeping with our treaty
obligations and with international law.� �Working closely with our network of allies and
partners, we will continue to promote a rules-based international order that ensures
underlying stability and encourages the peaceful rise of new powers, economic dynamism,
and constructive defense cooperation.
In the Middle East, the Arab Awakening presents both strategic opportunities and
challenges. Regime changes, as well as tensions within and among states under pressure to
reform, introduce uncertainty for the future. But they also may result in governments that,
over the long term, are more responsive to the legitimate aspirations of their people, and are
more stable and reliable partners of the United States.
Our defense efforts in the Middle East will be aimed at countering violent extremists and
destabilizing threats, as well as upholding our commitment to allies and partner states. Of
particular concern are the proliferation of ballistic missiles and weapons of mass destruction
(WMD). U.S. policy will emphasize Gulf security, in collaboration with Gulf Cooperation
Council countries when appropriate, to prevent Iran’s development of a nuclear weapon
capability and counter its destabilizing policies. The United States will do this while
standing up for Israel’s security and a comprehensive Middle East peace.� �To support these
objectives, the United States will continue to place a premium on U.S. and allied military
presence in – and support of – partner nations in and around this region.
Europe is home to some of America’s most stalwart allies and partners, many of whom have
sacrificed alongside U.S. forces in Afghanistan, Iraq, and elsewhere. Europe is our principal
partner in seeking global and economic security, and will remain so for the foreseeable
Sustaining U.S. Global Leadership: Priorities for 21st Century Defense 3
�
future. At the same time, security challenges and unresolved conflicts persist in parts of
Europe and Eurasia, where the United States must continue to promote regional security and
Euro-Atlantic integration. The United States has enduring interests in supporting peace and
prosperity in Europe as well as bolstering the strength and vitality of NATO, which is
critical to the security of Europe and beyond. Most European countries are now producers
of security rather than consumers of it. Combined with the drawdown in Iraq and
Afghanistan, this has created a strategic opportunity to rebalance the U.S. military
investment in Europe, moving from a focus on current conflicts toward a focus on future
capabilities. In keeping with this evolving strategic landscape, our posture in Europe must
also evolve. As this occurs, the United States will maintain our Article 5 commitments to
allied security and promote enhanced capacity and interoperability for coalition operations.
In this resource-constrained era, we will also work with NATO allies to develop a “Smart
Defense” approach to pool, share, and specialize capabilities as needed to meet 21st century
challenges. In addition, our engagement with Russia remains important, and we will
continue to build a closer relationship in areas of mutual interest and encourage it to be a
contributor across a broad range of issues.
Building partnership capacity elsewhere in the world also remains important for sharing the
costs and responsibilities of global leadership. Across the globe we will seek to be the
security partner of choice, pursuing new partnerships with a growing number of nations –
including those in Africa and Latin America – whose interests and viewpoints are merging
into a common vision of freedom, stability, and prosperity. Whenever possible, we will
develop innovative, low-cost, and small-footprint approaches to achieve our security
objectives, relying on exercises, rotational presence, and advisory capabilities.
To enable economic growth and commerce, America, working in conjunction with allies and
partners around the world, will seek to protect freedom of access throughout the global
commons – those areas beyond national jurisdiction that constitute the vital connective
tissue of the international system. Global security and prosperity are increasingly dependent
on the free flow of goods shipped by air or sea. State and non-state actors pose potential
threats to access in the global commons, whether through opposition to existing norms or
other anti-access approaches. Both state and non-state actors possess the capability and
intent to conduct cyber espionage and, potentially, cyber attacks on the United States, with
possible severe effects on both our military operations and our homeland. Growth in the
number of space-faring nations is also leading to an increasingly congested and contested
space environment, threatening safety and security. The United States will continue to lead
global efforts with capable allies and partners to assure access to and use of the global
commons, both by strengthening international norms of responsible behavior and by
maintaining relevant and interoperable military capabilities.
The proliferation of nuclear, biological, and chemical weapons technology has the potential
to magnify the threats posed by regional state actors, giving them more freedom of action to
challenge U.S. interests. Terrorist access to even simple nuclear devices poses the prospect
of devastating consequences for the United States. Accordingly, the Department of Defense
will continue to enhance its capabilities, acting with an array of domestic and foreign
partners, to conduct effective operations to counter the proliferation of WMD.

Primary Missions of the U.S. Armed Forces
To protect U.S. national interests and achieve the objectives of the 2010 National Security
Strategy in this environment, the Joint Force will need to recalibrate its capabilities and
make selective additional investments to succeed in the following missions:
x Counter Terrorism and Irregular Warfare. Acting in concert with other means of
national power, U.S. military forces must continue to hold al-Qa’ida and its affiliates and
adherents under constant pressure, wherever they may be. Achieving our core goal of
disrupting, dismantling, and defeating al-Qa’ida and preventing Afghanistan from ever
being a safe haven again will be central to this effort. As U.S. forces draw down in
Afghanistan, our global counter terrorism efforts will become more widely distributed
and will be characterized by a mix of direct action and security force assistance.
Reflecting lessons learned of the past decade, we will continue to build and sustain
tailored capabilities appropriate for counter terrorism and irregular warfare. We will also
remain vigilant to threats posed by other designated terrorist organizations, such as
Hezbollah.
x Deter and Defeat Aggression. U.S. forces will be capable of deterring and defeating
aggression by any potential adversary. Credible deterrence results from both the
capabilities to deny an aggressor the prospect of achieving his objectives and from the
complementary capability to impose unacceptable costs on the aggressor. As a nation
with important interests in multiple regions, our forces must be capable of deterring and
defeating aggression by an opportunistic adversary in one region even when our forces
are committed to a large-scale operation elsewhere. Our planning envisages forces that
are able to fully deny a capable state’s aggressive objectives in one region by conducting
a combined arms campaign across all domains – land, air, maritime, space, and
cyberspace. This includes being able to secure territory and populations and facilitate a
transition to stable governance on a small scale for a limited period using standing
forces and, if necessary, for an extended period with mobilized forces. Even when U.S.
forces are committed to a large-scale operation in one region, they will be capable of
denying the objectives of – or imposing unacceptable costs on – an opportunistic
aggressor in a second region. U.S. forces will plan to operate whenever possible with
allied and coalition forces. Our ground forces will be responsive and capitalize on
balanced lift, presence, and prepositioning to maintain the agility needed to remain
prepared for the several areas in which such conflicts could occur.
x Project Power Despite Anti-Access/Area Denial Challenges. In order to credibly deter
potential adversaries and to prevent them from achieving their objectives, the United
States must maintain its ability to project power in areas in which our access and freedom
to operate are challenged. In these areas, sophisticated adversaries will use asymmetric
capabilities, to include electronic and cyber warfare, ballistic and cruise missiles,
advanced air defenses, mining, and other methods, to complicate our operational
calculus. States such as China and Iran will continue to pursue asymmetric means to
counter our power projection capabilities, while the proliferation of sophisticated
weapons and technology will extend to non-state actors as well. Accordingly, the U.S.
military will invest as required to ensure its ability to operate effectively in anti-access

�
and area denial (A2/AD) environments. This will include implementing the Joint
Operational Access Concept, sustaining our undersea capabilities, developing a new
stealth bomber, improving missile defenses, and continuing efforts to enhance the
resiliency and effectiveness of critical space-based capabilities.
x Counter Weapons of Mass Destruction. U.S. forces conduct a range of activities aimed
at preventing the proliferation and use of nuclear, biological, and chemical weapons.
These activities include implementing the Cooperative Threat Reduction (Nunn-Lugar)
Program, and planning and operations to locate, monitor, track, interdict and secure
WMD and WMD-related components and the means and facilities to make them. They
also include an active whole-of-government effort to frustrate the ambitions of nations
bent on developing WMD, to include preventing Iran’s pursuit of a nuclear weapons
capability. In partnership with other elements of the U.S. Government, DoD will
continue to invest in capabilities to detect, protect against, and respond to WMD use,
should preventive measures fail. �
x Operate Effectively in Cyberspace and Space. Modern armed forces cannot conduct
high-tempo, effective operations without reliable information and communication
networks and assured access to cyberspace and space. Today space systems and their
supporting infrastructure face a range of threats that may degrade, disrupt, or destroy
assets. Accordingly, DoD will continue to work with domestic and international allies
and partners and invest in advanced capabilities to defend its networks, operational
capability, and resiliency in cyberspace and space.
x Maintain a Safe, Secure, and Effective Nuclear Deterrent. As long as nuclear
weapons remain in existence, the United States will maintain a safe, secure, and effective
arsenal. We will field nuclear forces that can under any circumstances confront an
adversary with the prospect of unacceptable damage, both to deter potential adversaries
and to assure U.S. allies and other security partners that they can count on America’s
security commitments. It is possible that our deterrence goals can be achieved with a
smaller nuclear force, which would reduce the number of nuclear weapons in our
inventory as well as their role in U.S. national security strategy.
x Defend the Homeland and Provide Support to Civil Authorities. U.S. forces will
continue to defend U.S. territory from direct attack by state and non-state actors. We will
also come to the assistance of domestic civil authorities in the event such defense fails or
in case of natural disasters, potentially in response to a very significant or even
catastrophic event. Homeland defense and support to civil authorities require strong,
steady–state force readiness, to include a robust missile defense capability. Threats to the
homeland may be highest when U.S. forces are engaged in conflict with an adversary
abroad.
x Provide a Stabilizing Presence. U.S. forces will conduct a sustainable pace of presence
operations abroad, including rotational deployments and bilateral and multilateral training
exercises. These activities reinforce deterrence, help to build the capacity and
competence of U.S., allied, and partner forces for internal and external defense,
strengthen alliance cohesion, and increase U.S. influence. A reduction in resources will

�
require innovative and creative solutions to maintain our support for allied and partner
interoperability and building partner capacity. However, with reduced resources,
thoughtful choices will need to be made regarding the location and frequency of these
operations.
x Conduct Stability and Counterinsurgency Operations. In the aftermath of the wars
in Iraq and Afghanistan, the United States will emphasize non-military means and
military-to-military cooperation to address instability and reduce the demand for
significant U.S. force commitments to stability operations. U.S. forces will nevertheless
be ready to conduct limited counterinsurgency and other stability operations if required,
operating alongside coalition forces wherever possible. Accordingly, U.S. forces will
retain and continue to refine the lessons learned, expertise, and specialized capabilities
that have been developed over the past ten years of counterinsurgency and stability
operations in Iraq and Afghanistan. However, U.S. forces will no longer be sized to
conduct large-scale, prolonged stability operations.
x Conduct Humanitarian, Disaster Relief, and Other Operations. The nation has
frequently called upon its Armed Forces to respond to a range of situations that threaten
the safety and well-being of its citizens and those of other countries. U.S. forces possess
rapidly deployable capabilities, including airlift and sealift, surveillance, medic
