Abstract:
The acts of terrorism committed by non-state actors on September 11, 2001 were promptly
responded by the use of force against Afghanistan, thus, commencing the ‘war on terror.’ This
thesis sets out the essential components of the international legal framework i.e. jus ad bellum and
jus in bello against which the September 11 attacks and the lawfulness of measures taken in
response, thereto, fall to be assessed. The main emphasis remains on relevant laws in relation to
the responsibility for 9/11 terrorist attacks, lawful constraints on the use of force in self-defense,
limitations on conduct of hostilities under the humanitarian principles and safeguards provided by
law-enforcement paradigm to protect basic human rights.
This study is, therefore, to highlight the existence of international legal regime capable of
addressing the events such as September 11 and governing the responses to that. It enquires the
compatibility of the ‘war on terror’ with the legal framework provided by international
law especially the Law of Armed Conflict in order to find out the legitimacy of use of force in
preemptive self-defense, conduct of military operations to prevent transnational terrorism,
targeted killings, collateral damage, detention operations and prosecution procedures. It also
refers to the implications for states responsible for noncompliance to the law and
subsequently for international rule of law. In this regard, the study explores that
interpretation of the law is significant that regulates the state-based rationale behind
compliance or noncompliance to the law. If there is a state-will to focus on humanitarian
protection of individuals then rationale is more related to the applicability of the law, and if a
state uses its influence and powerful status to achieve political-military objectives then rationale is
less concerned about the rule of law.
This proposition constitutes the threshold of applicability of the law in the ‘war on terror'
and eventually leads to the conclusion that unilateral use of force to counter terrorism is not a
viable solution rather it obscures international law as a legal framework in such military
operations. This thesis, thus, maintains that the existing international norms and standards can
only establish the rule of law, if states interpret the law in its simplest form, apply it regardless
of their vested interests and pay due respect to international legal regime.
