The Strait of Hormuz, a narrow waterway bordering Iran and Oman, is once again at the center of international concern. Recent escalations in the Middle East, following the attack on the Iranian consulate in Damascus and subsequent exchanges of fire between Israel and Iran, have raised the specter of a wider regional conflict. While New Zealand maintains a traditionally independent foreign policy, its commitment to international law and maritime security, coupled with its existing involvement in safeguarding shipping lanes, means Wellington could locate itself drawn into a potential conflict – a prospect carrying significant political and economic risks.
The principle of freedom of navigation – particularly through vital chokepoints like the Strait of Hormuz – is a cornerstone of international maritime law. This principle, rooted in historical precedent, was a contributing factor to the United States’ entry into World War I, demonstrating the high stakes involved in securing these crucial routes. Today, roughly 20% of the world’s oil supply passes through the Strait of Hormuz, making its security paramount for global energy markets. The U.S. Energy Information Administration details the strategic importance of this waterway.
On March 22, NATO Secretary-General Jens Stoltenberg announced that 22 countries, including New Zealand, were “coming together” to secure the Strait of Hormuz. While the New Zealand government has not issued a formal commitment to participate in any military action, nor has it explicitly ruled it out, the very fact of its inclusion in this grouping signals a level of engagement. This comes after New Zealand, in early 2024, joined a multinational effort to protect commercial shipping in the Red Sea from attacks by Houthi rebels in Yemen, a campaign linked to the conflict in Gaza. The Houthis have warned that any expansion of the conflict could have severe repercussions for global supply chains and energy prices.
The Legal Tightrope: International Law and Potential Intervention
The legal justification for any intervention in the region is complex and fraught with challenges. The United Nations Security Council has, in the past, framed Iranian actions as a “serious threat to international peace and security,” potentially legitimizing limited intervention by member states. However, this framing has been contentious, particularly given differing interpretations of international law regarding pre-emptive self-defense. The attacks on the Iranian consulate and the subsequent response have further muddied the waters.
Israel and the United States have asserted their actions were acts of self-defense against Iran’s nuclear ambitions, a justification permitted under international law. However, whether the criteria for pre-emptive self-defense were actually met remains highly questionable. Only the International Court of Justice (ICJ) possesses the authority to definitively rule on this matter. Currently, the ICJ is deliberating on the legality of Russia’s invasion of Ukraine, a case New Zealand has strongly supported. To maintain consistency in its foreign policy, Wellington would need to apply the same rigorous standards to the actions of the US and Israel regarding Iran, should the opportunity arise.
Professor Alexander Gillespie, a Professor of Law at the University of Waikato, highlights the precarious legal position. “It may be correct to defend a fundamental principle of international law supported by the UN Security Council,” he notes, “But there is only a paper wall separating that decision from a war against Iran that didn’t comply with the UN Charter in the first place.”
Echoes of Past Interventions and the Risks of Escalation
The current situation is further complicated by the illegal means employed by all sides. While Iran is accused of violating international humanitarian law and the UN Convention on the Law of the Sea through attacks on civilian and military facilities, the initial attacks that triggered the current crisis and subsequent retaliatory strikes, also raise serious legal questions. Russia’s targeting of civilian infrastructure in Ukraine serves as a stark reminder of the disregard for international law that can characterize modern conflicts. Even former U.S. President Donald Trump’s threats to “obliterate” Iranian energy facilities, though later postponed, underscored the potential for escalation and disregard for established norms.
The potential for strikes against or near nuclear facilities presents a particularly grave danger, carrying the risk of a humanitarian, environmental, and economic catastrophe. New Zealand’s influence in de-escalating the situation is limited, but Wellington can consistently remind all parties of their obligations under international humanitarian law. However, the historical record suggests that protecting the Strait of Hormuz may ultimately require a more substantial commitment, potentially including a ground presence to secure the coastline – a scenario reminiscent of the protracted interventions in Vietnam, Iraq, and Afghanistan.
The complexities are compounded by the domestic political landscape in New Zealand, which is heading towards a general election later this year. Any decision to commit New Zealand to military action would inevitably be subject to intense scrutiny and debate.
New Zealand’s Existing Commitments and the Broader Regional Context
New Zealand’s participation in Operation Prosperity Guardian, the multinational effort to protect shipping in the Red Sea, demonstrates a willingness to contribute to maritime security in the region. This deployment, involving a New Zealand naval vessel, reflects a commitment to safeguarding vital trade routes and upholding international law. However, the situation in the Strait of Hormuz presents a different set of challenges, given Iran’s direct involvement and the potential for a more direct confrontation.
The broader regional context is also crucial. The ongoing conflict in Yemen, the political instability in Iraq and Syria, and the complex relationship between Iran and Saudi Arabia all contribute to the volatile environment. Any escalation in the Strait of Hormuz could have far-reaching consequences, not only for the Middle East but for the global economy.
The potential for disruption to oil supplies, increased energy prices, and broader economic instability are all significant concerns. New Zealand, as a trading nation, would not be immune to these effects. The government will need to carefully weigh the risks and benefits of any potential involvement in a military response.
Looking ahead, the immediate focus will be on diplomatic efforts to de-escalate the situation and prevent a wider conflict. The United Nations Security Council is likely to play a key role in these efforts, but the effectiveness of any resolution will depend on the willingness of all parties to engage in good faith. New Zealand will continue to monitor the situation closely and assess the implications for its own national interests. The next significant development will likely be the outcome of ongoing diplomatic discussions and any further statements from the UN Security Council regarding the situation in the Strait of Hormuz.
