Which three pillars constitute the current U.S. National Security Strategy?

• A. Deterrence; Campaigning; Alliances
• B. Integrated Deterrence; Campaigning; Economic Tools
• C. Integrated Deterrence; Campaigning; Alliances/Partnerships
• D. Integrated Deterrence; Diplomacy; Alliances

Answer: (C)

The three pillars shaping the current U.S. National Security Strategy are Integrated Deterrence, Campaigning, and Alliances/Partnerships. Integrated Deterrence means combining military power with economic tools, diplomacy, cyber, and information efforts so any adversary faces credible, multi-domain consequences for aggression. Campaigning refers to ongoing, coordinated efforts across domains to shape the security environment, deter competitors, and seize opportunities through persistent competition rather than episodic actions. Alliances/Partnerships emphasize working with friends, allies, and partners to pool capabilities, share risk, and extend deterrence through greater interoperability and legitimacy.

This framing is the best fit because deterrence today relies on more than just military power; it requires a holistic, integrated approach that leverages partners and sustained influence. Campaigning provides the continual pressure and strategic shaping in a competitive landscape, while alliances and partnerships amplify effect and resilience by broadening access and capability. Other options miss one of these essential elements or treat a single instrument in isolation, which doesn’t capture how the current strategy organizes national security efforts.
