Key Points

To examine Stephen M. Walt's balance-of-threat theory of alliance formation by comparing it against Kenneth Waltz's balance-of-power theory and Randall Schweller's balance-of-interests theory.
Comparative analysis assessing Walt's (1988) balance-of-threat model against Waltz's (1979) structural balance-of-power theory.
Theoretical contrast of Walt's focus theory with Schweller's (1994) balance-of-interests framework, evaluating supporting evidence for each perspective.
Evidence supports Walt's balance-of-threat theory, demonstrating that states primarily form alliances in response to perceived threats rather than raw military power alone.
Empirical support is also identified for Schweller's balance-of-interests theory, indicating that state alignment choices also reflect opportunistic revisionist goals rather than purely defensive balancing.

Implication

Theoretical analysis reveals differing drivers of alliance formation in international relations, highlighting explanatory evidence for threat- and interest-based models.

Abstract

Stephen M. Walt’s “balance-of-threat” theory of alliance formation (1988) is examined as a focus theory. Walt’s theory is compared with a Kenneth A. Waltz’s “balance-of-power” as a supporting theory (1979), and supporting evidence for the focus theory is presented. Then, Walt’s theory is compared with Randall L. Schweller’s “balance-of-interests” as an opposing theory (1994), and supporting evidence for the opposing theory is presented.
