Adversary strategies seek to exploit perceived vulnerabilities in the American way of war now and into the future. Countering their attempts to challenge the Joint Force and weaken the foundations of a stable and open international system requires balancing near-term activities with mid- and long-term investments. The Joint Force needs new approaches to guide senior-leader decision making across time and the tools at our disposal. Key questions include: What frameworks or conceptual models can help clarify potential trade-offs between epochs? What decision support tools, including visualizations, can support senior decision-makers? What capabilities can allies offer to reliably provide bridge solutions? ARC submissions should develop a framework, conceptual model, or decision support tool that helps clarify these tradeoffs for senior decision-makers, using amplifying tools (e.g., visualization) as applicable.
