How Leaders' Beliefs Shape the Democratic Peace: Clinton, Blair, and Kosovo

Why This Question Matters

Do the personal beliefs of national leaders help explain why democracies rarely fight one another? Mark Schafer and Stephen G. Walker probe this puzzle by asking whether the operational codes—the coherent sets of beliefs leaders hold about the political world and the best strategies for action—help produce the democratic peace between states.

What Schafer and Walker Compare

The authors compare the operational codes of Prime Minister Tony Blair and President Bill Clinton and connect those beliefs to state behavior during the late-1990s Kosovo crisis. By focusing on two prominent democratic leaders who confronted the same international challenge, the study isolates how differences in leaders’ beliefs and styles shape dyadic interactions between democracies and nondemocracies.

How Operational Codes Are Understood Here

Operational codes refer to leaders’ beliefs about whether political opponents are friendlier or more hostile, the degree to which cooperation is possible, and the strategies appropriate for managing conflict. Schafer and Walker analyze those belief patterns for both leaders and relate them to the foreign-policy choices their governments made in Kosovo.

Key Findings

• Both Blair and Clinton viewed other democracies as relatively friendlier than nondemocracies and expressed more cooperative expectations toward democracies than toward nondemocratic states.
• Those asymmetric beliefs—more trust and willingness to cooperate with democracies—are reflected in their governments’ behavior during the Kosovo conflict, supporting a dyadic account of the democratic peace.
• Important individual differences also matter: Blair and Clinton displayed contrasting operational codes and leadership styles when dealing with nondemocracies, and these individual-level differences influenced how each managed the Kosovo crisis.
• The authors link stylistic differences to the domestic political cultures of the United Kingdom and the United States, suggesting context shapes how leaders translate beliefs into action.

Implications for Democratic Peace Research

The results bolster the dyadic version of the democratic peace by showing that leaders’ beliefs help produce friendlier relations between democracies; they also point scholars toward a more nuanced view in which the conflict behavior of democracies depends not only on regime type but on the calculations and styles of individual leaders when engaging nondemocratic states.
