While analysts hail the democratic peace as an empirical vindication of neo
idealist precepts of world politics, actually it is inconsistent with them.
Neoidealism focuses on the role of international regimes - not shared poli
tical regime type - in reducing the probability of interstate conflict. In
this article, I suggest a more consistent neoidealist conceptualization of
the stability among democratic dyads. Focusing on the postwar era, I mainta
in that a combination of factors, including bipolarity, nuclear deterrence,
alliance membership, and trade links, contributed to the formation of an i
nternational security regime among the major power democracies and their mi
nor power democratic allies. Further, I maintain that the presence of this
international regime and not simply joint democracy allowed for the postwar
stability among democratic dyads. While democracy may have been associated
with the creation of a security regime at the behest of the Western democr
acies led by the USA, the expansion and maintenance of this regime (and its
conflict dampening attributes) are rooted, to a greater extent, in the int
erplay of alliance-aggregation and security externalities of trade. This ar
gument is consistent with neoidealist precepts and by focusing on the role
of security regimes it contributes to the neoidealist research program.
