Which three themes were learned from war and crisis games?

• A. Alliances, Geography, Innovation
• B. Logistics, Industrial policy, Space
• C. Public opinion, Diplomacy, Trade
• D. Nuclear doctrine, Conventional forces, Cyber

Answer: (C)

War and crisis games highlight that what happens on the ground depends as much on political and economic forces as on military capabilities. Public opinion matters because leaders must weigh domestic support, political costs, and the legitimacy of actions before escalating or compromising. Diplomacy matters because crises are often resolved or managed through negotiations, alliances, sanctions, and international norms rather than through force alone. Trade matters because economic statecraft—access to resources, supply lines, sanctions, and budget pressures—can deter actions, compel concessions, or sustain a war effort.

While alliances, geography, and innovation influence outcomes, and while nuclear, conventional, or cyber capabilities are important, the trio that recurringly emerges in crisis simulations as defining levers are public opinion, diplomacy, and trade because they directly shape what leaders can do and what risks they are willing to take.
