The Domestic Determinants of Foreign Policy Behavior in Middle Eastern Enduring Rivals, 1948–1998

Rivalry-related issues tend to dominate the foreign policy agenda of states in enduring rivalries. Thus, the enduring rivalry research program provides an important framework for foreign policy analysis. This paper probes the domestic elements of strategic interaction in the three main Middle Eastern rivalries: Israel–Egypt, Israel–Jordan, and Israel–Syria. The empirical tests probe whether the number of parties represented in Israel's cabinet and Arab and Israeli domestic unrest impact the propensity for these rivals to employ hostility against each other. We specify vector autoregression (VAR) models and negative binomial event count models with monthly levels of hostility as the dependent variables for the period 1948–1998. The results provide interesting foreign policy implications regarding the impact of Israeli domestic political structures on conflict dynamics in the Middle East. There is no evidence that the foreign policy behavior of Arab states becomes risk averse when Israeli leaders might need an external scapegoat. These findings are discussed in the context of other research on enduring rivalries and strategic interaction.
