ABSTRACT
The object of this chapter is to consider the plausibility of the proposition that cooperation between adversaries in international politics tends to inhibit war between them. The proposition is not merely that joint measures to inhibit war tend to be effective. Nor is the proposition limited to the truism that peaceful agreement on an issue makes it less likely that war will occur over that issue. We will be concerned with a bolder claim in this chapter: cooperative interaction of whatever kind tends to reduce the probability of war over any issue, and thus the cumulative effect of sustained cooperation is to make war unlikely. This proposition is essential to internationalism, as pointed out previously.
