Constructivists have argued that interest-based explanations cannot fu
lly account for important international phenomena and that analysis of
the social construction of state identity may explain the genesis of
state interests. This argument can be applied to the early development
of neutral rights policy in the United States, when a weak and divide
d state clung to a policy that was opposed and consistently challenged
by far stronger powers. My explanation poses a principled conception
of identity: if leaders adopt a principle that constitutes a specific
international role for the state and commands domestic legitimacy, the
n diverse interests will converge on that principle, generating foreig
n policy continuity While neorealist and liberal institutionalist theo
ries each provide fragments of an explanation, a constructivist hypoth
esis comprehensively explains the relative continuity of the policy ov
er time.
