The Development of an Inter‐nation Tensiometer

Abstract

A nation’s military expenditure (M.E.) depends on its wealth (GNP), geography, and alliance memberships. This work develops a method to quantify inter-nation tension by first calculating a theoretical military expenditure (M.E.Th.) based solely on GNP, using data from 63 countries for the years 1964-1966. A “Tension Ratio” (T.R.) is then derived by dividing a nation’s actual M.E. by its M.E.Th. Statistical analysis demonstrates a significant correlation between high T.R. values and involvement in armed conflict. Of the nations engaged in war, 76.9% had a T.R. greater than 155, whereas only 26% of nations not at war exceeded this threshold. The association remains significant when comparing T.R. values to wars that occurred in subsequent years, suggesting that the T.R. can serve as a predictive tool to identify critical situations. The study also finds that geography (such as proximity to a hostile neighbor) and neutrality appear to have a greater impact on a nation’s tension level than membership in a military alliance. – AI-generated abstract.
