International agreements perform functions worthy of the closest attention of the student of international affairs. They are a principal tool of diplomacy and the aim of most negotiations. Many such agreements are not intended to create legal relationships, and the demarcation line between legally binding agreements and other consensual relationships is correspondingly hazy and uncertain. International agreements have not, however, received in recent times nearly the degree of attention devoted in international studies to “force” and “power.” This is so despite the fact that they generally reflect the participants' power calculations and shared expectations. They are an essential mode of guidance and regulation in international relations, helping to shape decisions and claims sometimes even in the course of armed conflicts. International agreements loom large in the actual experience of statesmen, jurists, and military men—their conclusion, their application, and their breach represent complex political decisions with frequently serious outcomes leading to shifts in power relationships.
