About Deterrence

Deterrence is a strategy that seeks to prevent an actor from taking specific action, and has been central to keeping peace for nearly 70 years. Applying the enduring concepts of deterrence requires a continuous effort to tailor as the security environment evolves.

NUCLEAR FORCES

A combination of flexible, diverse and resilient nuclear forces underpins effective deterrence. Intercontinental ballistic missiles on land and at sea, strategic bombers, nonstrategic nuclear forces, and a robust command and control system constitute U.S. nuclear forces.

MISSILE DEFENSE

Missile defense protects the United States, its military forces overseas, and its allies and partners from threats posed by hostile ballistic missiles of all ranges. The comprehensive approach consists of operations to neutralize, intercept and mitigate a potential missile attack.

MODERNIZATION

All three legs of the triad are approaching obsolescence and require modernization to ensure effective deterrence well into the 21st century. This modernization includes nonstrategic systems – dual-capable aircraft and pursuit of a sea-launched cruise missile.

TAILORED DETERRENCE

There is no "one size fits all" deterrence strategy. This demands adapting strategies to tailor them for potential adversaries over time, and a flexible mix of forces that are effective across a range of situations.

EXTENDED NUCLEAR DETERRENCE

The U.S. extends nuclear security guarantees to allies in Europe and Asia. This signals to adversaries the risks of threatening our allies’ vital interests. Providing security partners a reliable alternative to pursuing independent nuclear capabilities supports U.S. nonproliferation goals.

ARMS CONTROL

Well-conceived, carefully negotiated and clearly enforceable treaties contribute to stability. The United States is open to restoring a nuclear arms control dialogue with Russia once Russia returns to full compliance with its existing treaty obligations.

In light of the realities of the contemporary threat environment, the 2018 NPR presents an assessment of US nuclear policy that is consistent with past US policy by placing priority on the need to deter potential adversaries, assure allies and partners, and hedge against future risks, while also seeking greater cooperation where possible in support of arms control and global non-proliferation efforts.
