This article compares the Hobbesian realist and Kantian idealist analyses of
international law and organizations with respect to the UN General Assembly
resolutions and the International Court of Justice (ICJ) advisory opinion on
Israel's separation barrier. From the realist perspective, this case
highlights the exploitation of moral claims in support of a particularist
political agenda. In contrast, the idealist approach interprets the advisory
opinion and resolutions as important normative expressions in the developing
global system of governance based on universal human rights principles and
treaty obligations.
The analysis begins with a detailed comparison of the ideological and
intellectual foundations of these core approaches to international law and
organizations, the evolution of this debate in the post Cold War
international system, and the impact on protracted ethno-national conflicts.
This provides the basis for examining the impact of both schools in the
context of the Arab-Israeli conflict. The specific case of the UN and ICJ's
involvement in the question of Israel's separation barrier is then analyzed
in detail from both the realist and idealist perspectives.
The implications of this debate are of major importance, not only with
respect to the specific challenges posed by terrorism and the necessary
responses, but also in the wider context of the crisis in the international
system at the beginning of the 21st century. The analysis
concludes by noting the degree to which this case illustrates a wider
process in which international legal principles are manipulated in a manner
that contributes to conflict and justification of violence, conforming to
the realist interpretation. While still pursuing idealist objectives,
wishful thinking cannot conceal the abuse ofuniversalist claims of morality
in the pursuit of war by other means.
