given in text. The distance between an intervener and a target is measured along a 5-point scale: (1) 0-500 miles, (2) 501-1500 miles, (3) 1501-3000 miles, (4) 3001-5000 miles and (5) greater than 5000 miles. Dichotomous measures of the relative power of the intervener ("large" if 1 or 2; "small" otherwise) and affect employed.
Data Analysis: chi-squares, gamma statistics, frequency tables and tree diagrams.
Finding: Fifty two percent of the 141 interventions identified between 1948 and 1967 were made with the goal of changing the policy of the target state; forty eight percent to quell a domestic dispute. Fifty percent of the interventions were classified as "hostile"; 43 % as "friendly". Interventions were much more likely to be "friendly" if the goal was to quell a domestic dispute. They were much more likely to be "friendly" if the goal was to change a target's policies or internal conditions [Table 2]. There is a strong positive and significant correlation (gamma = +.65) between the "size" of an intervener and the geographic distance between it and the target of its interventions [Table 4]. This finding is generally consistent when controls were made for the size of the initiator relative to the target [Table 6]. "Large" states are more prone (76 % of the cases) to intervene on behalf of a friendly state than a hostile one, and are equally likely to intervene with the goal of quelling a domestic dispute or changing a target's policies. "Middle" and "small" states are much more prone (64 % of the cases) to intervene in a hostile state than a friendly one, and are equally as likely to intervene with the goal of quelling a domestic dispute as changing a state's policies [Table 5].
