Prime Minister Mark Carney has publicly expressed his support for recent U.S. and Israeli air strikes on Iran, albeit with a sense of regret, underscoring the complexities of international law and the deteriorating state of global governance. In comments made during his visit to Sydney, Australia, Carney articulated a nuanced stance that reflects both his concerns about Iran’s activities and his disquiet over the manner in which the strikes were executed.
A Cautious Endorsement
In a press briefing on Wednesday, Carney described Iran as a significant threat to stability in the Middle East, yet he stressed that the military actions taken by the U.S. and Israel represented a concerning deviation from established international norms. “While we support these actions based on the need to curb Iran’s aggressive posture, we do so with regret,” Carney remarked. This sentiment reveals his attempt to distance himself from the unilateral decisions made by U.S. President Donald Trump and Israeli Prime Minister Benjamin Netanyahu.
Carney’s comments follow a statement released on Saturday, marking his first remarks regarding the strikes. He cautioned that the ongoing conflict exacerbates an already fragile situation, leading to “a rapidly spreading conflict and growing threats to civilian life” in the region. Iran has retaliated against Israel and U.S. military installations, prompting further escalation.
Legal Implications and International Norms
Addressing the legal ramifications of the pre-emptive strikes, Carney articulated that they “prima facie, appear to be inconsistent with international law.” He underscored the need for the U.S. and Israel to provide justifications for their actions under international law, leaving the determination of legality to legal experts. “That formal judgment is for others to make,” he stated, indicating that Canada would not be involved in military operations related to this conflict.

The Prime Minister lamented the apparent failure of the international order, drawing parallels to his earlier speech at the World Economic Forum in January, where he declared that the existing rules-based system is increasingly ineffective. “Despite decades of UN Security Council resolutions and various diplomatic frameworks, the threat posed by Iran remains unaddressed,” Carney asserted, highlighting Canada’s exclusion from discussions surrounding the strikes.
Canada’s Stance on Iran
Canada’s relationship with Iran has grown increasingly strained over the past fifteen years. The cessation of diplomatic ties initiated by former Prime Minister Stephen Harper in 2012 has never been reversed, and Prime Minister Justin Trudeau has remained a vocal critic of Iran, particularly following the 2020 downing of a commercial plane that resulted in the deaths of Canadian citizens. In 2024, Canada officially designated Iran’s Islamic Revolutionary Guards Corps as a terrorist entity.
While Carney has reiterated Canada’s commitment to preventing Iran from acquiring nuclear weapons, he also made it clear that Canada’s support for the strikes is not unconditional. “We remind all belligerents of their responsibilities to protect civilians and civilian infrastructure, urging de-escalation in this volatile situation,” he said.
Internal Criticism and Diverse Opinions
The Prime Minister’s endorsement of the strikes has not gone uncontested within Canadian political circles. Former Liberal cabinet minister Lloyd Axworthy has been vocal in his criticism, arguing that the air strikes lacked United Nations authorisation and contrasting the current administration’s position with Canada’s refusal to support the U.S. invasion of Iraq in 2003 for similar reasons. Liberal MP Will Greaves echoed these concerns, stating, “Canada cannot endorse the unilateral and illegal use of military force.”

When confronted with dissent from members of his own party, Defence Minister David McGuinty responded that the Liberal Party is inherently diverse, allowing for a range of perspectives. “This reflects Canadian society,” he noted, emphasising the importance of open dialogue and debate.
Why it Matters
Carney’s remarks underscore a pivotal moment in Canada’s foreign policy, revealing the delicate balance the government seeks to maintain between supporting allies and adhering to principles of international law. The Prime Minister’s caution signals a broader concern about the implications of unilateral military action and its potential to undermine global stability. As tensions rise in the Middle East, Canada’s approach may serve as a barometer for other nations grappling with similar dilemmas in the context of international relations.
