The use of force and coercion to settle disputes between nations is a central problem of our time. Martin Patchen considers the circumstances that lead nations to use coercive means in disputes with other nations and also examines the effectiveness of other means of resolving international disputes. Patchen examines conflict and cooperation as general social processes and builds on previous work to present an overall theoretical framework that encompasses the conflict situation, perceptions of the adversary, decision-making, bargaining, and interaction and influence sequences.
