خلاصه	The Richardson arms race model, set out by Lewis Fry Richardson in Arms and Insecurity (1960), is a pair of coupled differential equations describing how two rival states adjust their armaments over time. Each state's rate of arming rises with the rival's level of arms (action–reaction fear), falls with the burden of its own existing arms (fatigue or economic constraint), and is shifted by underlying grievance or goodwill. Analyzing the system reveals whether an arms race converges to a stable equilibrium or spirals upward without bound, making it the foundational mathematical model of arms competition.	Militarized interstate dispute (MID) analysis is the coding and quantitative study of confrontations in which one state threatens, displays, or uses military force against another. Built on the Correlates of War project's MID dataset and the coding rules codified by Jones, Bremer, and Singer (1996), it provides the standard observational measure of interstate conflict short of and including war, structured as dyad-years so that the onset, escalation, and outcomes of disputes can be modeled statistically across two centuries of the international system.
