Why Canada Should Not Support an Israeli Attack on Iran

The Canadian newspapers reported this week that Prime Minister Netanyahu would be seeking the support of the Canadian government for a possible military attack on Iran. There is increasing speculation that Israel will launch military strikes before summer against the nuclear enrichment facilities within Iran, in an attempt to prevent Iran from developing nuclear weapons. Prime Minister Harper has given Netanyahu hope that Canada might back such a move. But the strikes would violate international law, and Canadian support for them would utterly betray the values that Canada has long championed.

First, let us examine the legality. The international law regime under the United Nations system prohibits all use of armed force, except in self-defence in the event of an armed attack, or for collective security purposes as authorized by the U.N. Security Council. The Israelis are trying to characterize the proposed military strikes as acts of self-defence to prevent an existential threat from materializing. Such strikes would not, however, satisfy the test for self-defence.

While there is some agreement in international law that states can use force to defend against an imminent armed attack, rather than being required to wait for the first blow to actually fall, the test for imminence is strict. Such “anticipatory self-defense” is permitted only when the “necessity of self-defense is instant, overwhelming, and leaving no choice of means and no moment for deliberation” (a formulation that arose from an incident between Britain and the U.S. in 19th-century Canada, as it happens). In contrast, there has been widespread rejection of the concept of “preventative self-defense” — that is, the use of force to prevent the development of a more distant and speculative future threat. … Read more…

The Legal Implications of Military Intervention in Libya

(Published in The Huffington Post, March 2, 2011)

As the crisis in Libya deepens there is increasing chatter about the possibility of military intervention. At the moment this is suggested most frequently in the form of a no-fly-zone over Libya, in order to prevent Gaddafi from using the air force against civilian protestors.

A debate is developing over the wisdom of any American or Western military involvement, but as usual there is little being said about the international law principles that would be implicated by such operations. And in the context of the growing unrest throughout the region, perceptions of the legality or illegality of any U.S. military action could have a significant impact on the developing narrative in the Arab world regarding America’s role, and how the emerging regimes ought to frame their relations with the U.S. going forward. The law matters in this situation.

The starting point of the legal analysis is the basic prohibition in international law on the use of armed force against the territorial integrity or political independence of any state. The two primary exceptions to the prohibition are self-defense, which is obviously not applicable here, and operations authorized by the United Nations Security Council in response to a threat to international peace and security. There is no question, therefore, that if the U.N. Security Council passed a resolution authorizing the imposition of a no-fly-zone in order to maintain peace and security in and around Libya, as it did in Iraq in the 1990s, the U.S. and its NATO allies could do so with the full imprimatur of international law.
