II. Counter-Terrorism and the Use of Force in International Law - Michael Schmitt1.

era in international security affairs. Although terrorism has been a tragically prominent feature of the global condition for most of the past half century, these operations were quantitatively and qualitatively different than those of the past. They involved extensive and sophisticated long-term planning by a group that cuts across lines of nationality and which operates from within many countries.2 The scale of the destruction in both human and physical terms was shocking; the fact that the attacks and their aftermath were broadcast live only served to further exacerbate their psychological impact.

2. For an excellent discussion of how the attacks were a turning point in the evolution of international terrorism, see Paul J. Smith, Transnational Terrorism and the al Qaeda Model:

Confronting New Realities, PARAMETERS, Summer 2002, at 33. See also, Michael Howard, What's in a Name? How to Fight Terrorism, FOR. AFF'S, January/February 2002, at 8, which argues that declaring a 'war' on terrorism was a 'terrible and irrevocable error.' Id. at 8.

That all 19 terrorists directly involved executed them with great precision despite the certainty of their own deaths may well portend a terrifying face of 21st century terrorism-a genre of terrorism likely to prove extraordinarily difficult to counter by traditional means.

Combating this aggravated form of terrorism will require new cooperative security strategies. Certainly, the Global War on Terrorism articulated by the United States represents one such strategy.3 As time passes and opportunities and threats become clearer, the worldwide war on terrorism will evolve responsively. Other governments and intergovernmental organizations are already developing parallel and complimentary strategies.

Lest the lawlessness inherent in terrorism spread to its victims, counterterrorism strategy must be formulated with great sensitivity to the international law governing the use of force. Some have suggested that this body of law, including that facet regarding the right to self-defense, is not up to the task4

3. The extent to which the GWOT represents a fundamental shift in US strategies for dealing with threats is apparent in President Bush's discussion of preemptive strategies. See Remarks by the President at 2002 Graduation Exercise of the United States Military Academy, June 1, 2002, available at http://www.whitehouse.gov/news/releases/2002/06/20020601-3.html Gun. 18, 2002).

Released on September 17, 2002, the US National Security Strategy incorporates such strategies.

See U.S. National Security Strategy, at 4, available at http://www.whitehouse.gov/nsc/nss.html (Nov. 4, 2002).

4. See Michael J. Glennon, The Fog ofLaw: Self-Defense, Inherence, and Incoherence in Article 51 of the United Nations Charter, 25 HARV. J. L. & PUB. POL. 539 (2002). Professor Glennon argues that:

The international system has come to subsist in a parallel universe of two systems, one de jure, and the other de facto. The de jure system consists of illusory rules that would govern the use of force among states in a platonic world of forms, a world that does not exist. The de facto system consists of actual state practice in a real world, a world in which states weigh costs against benefits in regular disregard of the rules solemnly proclaimed in the all-but-ignored de jure system. The decaying de jure catechism is overly schematized and scholastic, disconnected from state behavior, and unrealistic in -its aspirations for state conduct.

Others counter that effective responses to terrorism and state 'supporters' thereof are proving entirely consistent with existing prescriptive norms.5 This article explores those norms, specifically the relevant jus ad bellum,6 in the context of the response to the 9/11 attacks. Under what circumstances can a victim state react forcibly to an act of terrorism? Against whom? When? And with what degree of severity? It concludes that a natural evolution in the community understanding of limitations on the use of force has occurred over the past decades, such that claims of international law's present insufficiency are overblown. However, assertions that the law as traditionally understood supports a full range of forceful responses to terrorism equally overstate reality. As is usually the case, the truth lies between the extremes.

The Relevant Facts In order to effectively appraise the international law governing the use of force in counter-terrorism today, and to acquire a sense for its normative vector, it is necessary to first paint the factual backdrop. Law tends to be reactive and responsive to the factual context in which it operates; Obviously, this is the case for customary international law, which relies, inter alia, on state practice for its emergence. The same is true, however, for convention-based law. Despite declarations that international agreements, such as the UN Charter, should be interpreted in accordance with the ordinary meaning of their text, it is undeniable that community understanding of law shifts over time to remain 5. See, e.g., Jack M. Beard, America's New War on Terror: The Case for Self-Defense Under International Law, 25 HARV. J. L. & PUB. POL. 559 (2002).

[T]he case for America's forcible response to the September 11 attacks as being fully consistent with the inherent right of self-defense under customary international law and Article 51 of the U.N. Charter is very strong. The unanimous condemnation of the attacks by the U.N. General Assembly, the affirmation of the right of self-defense by the Security Council, the growing consensus in the international community to hold states accountable for terrorist actions, and the repeated condemnation by the Security Council of the Taliban Regime's support of terrorists in particular, clearly help establish an appropriate framework under international law for the exercise of self-defense by the United States.

6. That component of international law that governs when it is that a state may resort to force in pursuit of its national interests, such as defending itself from armed attack.

coherent and relevant to both current circumstances and the global community's normative expectations.7

Sadly, the facts of 9/11 are all too familiar. On 11 September 2001, terrorists seized control of four passenger aircraft in the United States. Two were flown into the Twin Towers of the World Trade Center in New York City, a third was driven into the Pentagon in Washington D.C. and the fourth crashed in Pennsylvania following an unsuccessful attempt by passengers to regain control from the highjackers. Roughly 3000 people of over 80 nationalities perished.

Investigation quickly led authorities to focus their attention on Osama bin Laden and his al Qaeda terrorist organization.8 Al Qaeda operates from more than 60 countries through a compartmentalized network using operatives of numerous nationalities. By October, the British government felt sufficiently confident in intelligence reports at its disposal to release certain facts and conclusions regarding the group. These were subsequently confirmed by the United States. Specifically, 10 Downing Street announced that al Qaeda had planned and conducted the attacks, that it continued to have the resources to mount further operations, that US and UK citizens were potential targets and that 'Usama Bin Laden and Al-Qa'ida were able to commit these atrocities 7. Pursuant to Article 31 of the Vienna Convention on the Law of Treaties:

2. There shall be taken into account together with the context:...

679 (1969). This point was reiterated by the International Court of Justice in Competence of the General Assembly for the Admission of a State to the United Nations. There, the Court noted 'the first duty of a tribunal which is called upon to interpret and apply the provisions of a treaty is to endeavour to give effect to them in their natural and ordinary meaning in the context in which they occur.' 1950 I.C.J. 4, 8.

because of their close alliance with the Taleban regime, which allowed them to operate with impunity in pursuing their terrorist activity.'9

Of particular relevance to the use of force issue is the fact that al Qaeda was hardly venturing into terrorism for the first time on September 11th. The organization had allegedly been involved in the 1993 World Trade Center bombing, the 1998 bombings of the US embassies in Kenya and Tanzania (attacks for which Osama bin Laden has been indicted10), and...
