In democratic peace theory, what factors are cited to explain fewer wars between democracies?

• A. Geographic proximity and shared borders.
• B. Norms, transparency, and institutional constraints.
• C. Economic interdependence only.
• D. Military power parity.

Answer: (B)

Democratic peace theory argues that democracies are less likely to go to war with one another because their political systems share certain habits and constraints. The idea is that norms favor resolving disputes through dialogue and legal institutions rather than force, so leaders face domestic expectations to avoid costly wars that would be unpopular with citizens and opposition groups. This makes peaceful competition and collaboration more common between democracies.

Transparency plays a key role as well. When states operate in open political environments, intentions and capabilities are easier to observe, reducing misperceptions and miscalculations about the other side’s resolve. Clear information and regular scrutiny by the press and the public help prevent reckless moves that could lead to conflict.

Institutional constraints are crucial too. Democracies require broad consent from legislatures, courts, and the public before entering major wars. This makes leaders more cautious about going to war, especially against another democracy where the costs and casualties would be politically costly and heavily scrutinized. The combination of shared norms, transparency, and institutional checks helps explain why wars between democracies are comparatively rare.

Geographic proximity, while it can raise risk for some conflicts, is not the mechanism that accounts for fewer wars between democracies. Economic interdependence and military power parity are related factors in international politics, but they do not as directly capture the specific democratic mechanisms that reduce interstate war between democracies.
