Which of the following is one of the four main defense priorities?

• A. Expand overseas bases
• B. Increase civil-military education programs
• C. Strengthen alliance interoperability
• D. Build a resilient Joint Force

Answer: (D)

The main idea here is that building a resilient Joint Force is the foundational goal for ensuring the U.S. military can deter and defeat adversaries across all domains, even under pressure or in disrupted conditions. A resilient Joint Force means forces that are designed, trained, and sustained to operate effectively in contested environments, maintain command and control, and continue mission essential operations even when faced with heavy stress, cyber or space threats, or supply and maintenance challenges. It involves robust logistics, redundancy, interoperability across services, and the ability to recover quickly from setbacks, all of which keep the military capable and ready at all times.

This resilience supports staying power and credibility in deterrence and is a unifying priority that shapes modernization, force design, readiness, and alliance work. By prioritizing resilience, the forces can adapt to future threats, operate with partners more smoothly, and sustain operations longer if needed.

Expanding overseas bases, while important for presence and posture, is more about footprint decisions than the overarching strategic aim. Civil-military education programs, though valuable for civil-military relations and informed leadership, are not the central strategic priority. Strengthening alliance interoperability is crucial and closely tied to joint operations, but it fits within broader partnership and readiness efforts rather than standing alone as one of the four main defense priorities.
