Peacekeeping: a Strategic Approach

Abstract

This paper presents a theoretical model of conflict between two players, with intervention by a peacekeeping force. Peacekeepers are treated as a military contingent, capable of taking sides, acting as a third (independent) side in the war, or remaining inactive, depending on circumstances. This departs from previous models, in which peacekeeping was no more than a parameter affecting players' fighting costs. The main result is an optimal deployment strategy by peacekeepers, detailing the nature and level of intervention required under different circumstances; a strategy which results in the lowest possible level of warfare between the two antagonists. The credible threat of force (rather than mere intervention) is the strategy's key component.
