In this report, RAND researchers explore the factors, contexts, and mechanisms that shape a national government’s decision to continue or end military and other operations during a conflict (i.e., national will to fight). To help U.S. leaders better understand and influence will to fight, the researchers propose an exploratory model of 15 variables that can be tailored and applied to a wide set of conflict scenarios.

"What drives some governments to persevere in war at any price while others choose to stop fighting? It is often less-tangible political and economic variables, rather than raw military power, that ultimately determine national will to fight. In this analysis, the authors explore how these variables strengthen or weaken a government's determination to conduct sustained military operations, even when the expectation of success decreases or the need for significant political, economic, and military sacrifices increases. This report is part of a broader RAND Arroyo Center effort to help U.S. leaders better understand and influence will to fight at both the national level and the tactical and operational levels. It presents findings and recommendations based on a wide-ranging literature review, a series of interviews, 15 case studies (including deep dives into conflicts involving the Korean Peninsula and Russia), and reviews of relevant modeling and war-gaming. The authors propose an exploratory model of 15 variables that can be tailored and applied to a wide set of conflict scenarios and drive a much-needed dialogue among analysts conducting threat assessments, contingency plans, war games, and other efforts that require an evaluation of how future conflicts might unfold. The recommendations should provide insights into how leaders can influence will to fight in both allies and adversaries."--Publisher's description.
