In a nuanced statement delivered during his visit to Sydney, Australian Prime Minister Mark Carney expressed a conflicted stance regarding the recent air strikes launched by the United States and Israel against Iran. While recognising Tehran as a significant threat to regional stability, Carney articulated his concerns that these pre-emptive military actions represent a failure of the international legal framework, raising questions about their legitimacy under international law.
A Divided Stance
Prime Minister Carney’s comments come as part of a broader effort to clarify Canada’s position in the escalating conflict. He expressed support for the strikes “with regret,” highlighting the complex dynamics of international relations. “We do, however, take this position with regret, because the current conflict is another example of the failure of the international order,” he stated, further distancing himself from U.S. President Donald Trump and Israeli Prime Minister Benjamin Netanyahu’s actions.
The Prime Minister emphasised the repercussions of these military strikes, noting that they have sparked a “rapidly spreading conflict” and heightened dangers to civilian lives throughout the region. As Iran retaliates against Israel and U.S. military installations in neighbouring countries, Carney underscored that the situation could escalate further into a larger crisis.
The Legal and Moral Implications
Carney’s remarks about the legality of the strikes were pointed. He asserted that the pre-emptive nature of the attacks “prima facie, appear to be inconsistent with international law,” and indicated that the burden of proof lies with the U.S. and Israel to justify their actions within the bounds of international norms. “That formal judgment is for others to make,” he noted, suggesting that legal scholars and international bodies should weigh in on this contentious issue.

Reflecting on the broader implications, Carney lamented the apparent breakdown of the rules-based international order, a theme he previously explored in his January address at the World Economic Forum. He reiterated that the failure to consult allies, including Canada, before taking such military actions undermines the collaborative spirit that should govern international relations.
Canada’s Firm Stance on Iran
Canada’s position toward Iran has evolved significantly over the years. Following the severance of diplomatic ties by former Prime Minister Stephen Harper in 2012, the Trudeau government has maintained a critical stance, especially after the 2020 incident involving the downing of a Ukrainian airliner that resulted in the deaths of several Canadians. In 2024, Ottawa designated Iran’s Islamic Revolutionary Guards Corps as a terrorist entity, a move that underscores the deteriorating relationship between Canada and Tehran.
While Carney underscored the importance of preventing Iran from acquiring nuclear weapons, he was careful to clarify that Canada’s support for the strikes does not equate to a “blank cheque” for U.S. and Israeli actions. He stressed the necessity for all parties involved to adhere to international humanitarian obligations, particularly regarding civilian safety. “We remind all the belligerents of their responsibilities to protect civilians,” he urged, calling for a de-escalation of hostilities.
Diverging Opinions Within Canada
The Canadian government’s backing of the strikes has not gone unchallenged. Former Liberal cabinet minister Lloyd Axworthy has voiced strong criticism, arguing that the military action lacks UN authorisation and contrasts sharply with Canada’s stance during the 2003 Iraq invasion, which was similarly not sanctioned by the Security Council. Liberal MP Will Greaves echoed these sentiments, cautioning against endorsing unilateral military force that could lead to civilian casualties and undermines the principles of sovereignty and independence.

In response to this dissent from within his own party, Defence Minister David McGuinty acknowledged the diversity of opinions within the Liberal Party. “The Liberal Party is a big tent. There’s room for all kinds of competing views,” he remarked, highlighting the importance of open dialogue in shaping Canada’s foreign policy.
Why it Matters
Carney’s cautious endorsement of U.S. and Israeli military action against Iran encapsulates the delicate balancing act that Canada must navigate in a rapidly shifting geopolitical landscape. While the government seeks to align itself with allies in the face of perceived threats, it also grapples with the moral and legal implications of such actions. The debate within Canadian political circles reflects broader societal concerns about the role of military intervention in international relations. As tensions rise, the need for a coherent, principled approach to foreign policy has never been more critical.
