The Failures of the Courts

After the Vietnam War, it seemed like the world finally got how bad industrial warfare could be for the environment. New protections were put in place, but the job of enforcing them went to international legal bodies that were more focused on state sovereignty and military needs than on protecting ecosystems. Michael Bothe and Carl Bruch point out that while international humanitarian law began recognizing the environment as a legal issue post-Vietnam, enforcement remained in the hands of the same political players who caused the damage. The article A Critical Defence of the Crime of Ecocide highlights this contradiction: even though environmental harm was legally acknowledged, it was tough to enforce because it depended on state consent rather than independent legal authority. This is why, despite years of environmental assessments and treaties, international courts have struggled to hold states accountable for ecological damage during war.

The Rome Statute of the International Criminal Court is a prime example of this issue. Article 8(2)(b)(iv) only criminalizes environmental damage if it's "widespread, long-term, and severe," and even then, only if it's "clearly excessive" compared to the expected military gain. This language is similar to earlier standards but adds more ambiguity, limiting its use. Cymie Payne notes that despite being drafted after the Gulf War's oil fires, the Rome Statute's high bar for environmental crimes has stopped any real criminal prosecution. Courts have to balance environmental destruction against military advantage, putting the burden on scientific and legal authorities while still favoring military decisions. In reality, this means environmental destruction is seen as an unfortunate side effect of conflict, not a war crime.

The International Court of Justice (ICJ) shows a similar trend of recognizing issues without enforcing change. The Court acknowledges environmental protection as a legal duty but rarely challenges state military actions. It stresses that states should prevent serious environmental harm, but lacks the power to enforce this. This becomes obvious in modern conflicts. As Kaamil Ahmed and Damien Gayle report on Gaza, the ICJ recognizes large-scale environmental destruction, but real action depends on political referrals and state cooperation, not automatic jurisdiction. The Court's reliance on advisory opinions reveals the same weaknesses seen post-Vietnam.

The United Nations' post-conflict efforts have reinforced this pattern instead of fixing it. After the 1991 Gulf War, the UN Compensation Commission (UNCC) compensated Kuwait for environmental damage caused by Iraq's oil fires but didn't pursue criminal accountability. One scholar calls this a clear example of the UN's reluctance to challenge state actions during war, prioritizing political stability and reconstruction over enforcing environmental norms. So, one of the worst environmental disasters of the 20th century was treated as a compensable civil offense, not a prosecutable humanitarian law violation. This compensation model shows the UN's institutional weakness and reluctance to uphold international law in the name of "stability."

This approach continues today. In Ukraine, researchers have documented environmental damage from Russia's invasion, but there's been no significant prosecution by the ICC or ICJ. Legal experts like Mark Nevitt argue this failure is an institutional problem, not a lack of evidence. International courts aren't set up to handle the environmental fallout of modern war because they focus more on immediate human casualties than on slow-moving ecological destruction. Similarly, the United Nations Environment Programme's 2024 Gaza assessment warns of environmental collapse, but the legal response has been mostly symbolic. In both cases, the destruction is noted and reported, but enforcement mechanisms fail to be used.

This enforcement gap has sparked growing criticism. Joanna Jarose argues that while the ENMOD Convention could limit environmental manipulation, its prohibitions are rarely used because enforcement bodies prioritize state interests and military justifications. Clark suggests that modern conflicts show how international law is still anthropocentric, recognizing environmental damage only when it directly affects humans. These limitations have prevented courts from adapting to industrial warfare realities, where environmental destruction is often deliberate and long-lasting.

Overall, the history of post-Vietnam legal development shows that the failure of enforcement institutions isn't by accident. The legal framework for protecting the environment during war has grown since the 1970s, but the institutions applying it remain constrained by politics and military priorities. The ICC and ICJ can recognize environmental harm but aren't willing or able to prosecute it. As a result, the environment remains one of the least protected victims of modern warfare, showing that while wartime environmental law has evolved since Vietnam, its enforcement is still lacking.

Since the Vietnam War, the inability of international courts to prosecute large-scale environmental destruction has led to a push for reform. The concept of ecocide, first mentioned during Vietnam to describe deliberate ecosystem devastation, has resurfaced as a framework for addressing environmental harm in modern war. Vietnam's defoliation campaigns made it clear that the environment was a target in war, reshaping global environmental awareness. Emmanuel Kreike traces a history of "scorched-earth" warfare, arguing that modern militaries have often targeted the natural world. These works show that ecocide isn't just rhetorical but a historically grounded concept reflecting how environmental destruction has been normalized in military strategy. The resurgence of this language indicates a growing recognition that international law hasn't kept pace with war's ecological consequences.

The United Nations International Law Commission's 2022 Draft Principles on the Protection of the Environment in Relation to Armed Conflicts is a clear response to this failure. These principles attempt to outline environmental obligations before, during, and after hostilities. They call for states to prevent environmental harm, conduct impact assessments, and ensure post-conflict remediation. Karen Hulme sees this as a significant step beyond ENMOD and Protocol I, integrating environmental protection into humanitarian and criminal law. But the principles also highlight international law's persistent weaknesses. Like ENMOD and Additional Protocol I, they depend on voluntary state adherence, not binding enforcement. So, they show both progress and limitation: increased awareness of wartime environmental harm but enforcement remains politically limited.

Recent scholarship focuses on how existing international environmental law could be applied more effectively during and after conflict. Hulme’s work on biodiversity suggests conservation frameworks could legally protect vulnerable ecosystems during war. Mark Nevitt and J. N. Clark argue that current legal regimes are still too anthropocentric, prioritizing human suffering over environmental recovery. They say international law's failure isn't just about enforcement but about how it's framed. By treating the environment mainly as a resource for human survival, current frameworks limit their own effectiveness.

The push for reform is also coming from civil society and academics. The Stop Ecocide Foundation and legal scholars want ecocide recognized as an international crime under the Rome Statute of the ICC. Joanna Jarose argues this could turn ENMOD's symbolic prohibitions into a viable legal standard for prosecuting environmental modification as a war crime. Isabela Pizarro's analysis of environmental destruction in Palestine frames recent Gaza conflicts as ecocide, showing the issue identified in Vietnam still exists. These reform movements highlight the gap between legal recognition and accountability. While environmental harm is documented, the ICC and ICJ remain reluctant to prosecute without Security Council referral or state consent.

Current conflicts have made these reform debates urgent. In Gaza, UN assessments describe water system collapse and long-term health impacts, echoing the ecocide language from Vietnam. In Ukraine, researchers document industrial contamination and ecosystem damage from the Russian invasion. These studies show war's environmental impacts aren't hypothetical; they affect post-conflict recovery and raise questions about how international law defines humanitarian harm. Yet, as in earlier wars, these findings haven't led to consistent legal action. Courts recognize environmental devastation, but enforcement is uncertain and mostly symbolic.

Overall, the renewed focus on ecocide and environmental reform shows a shift in both environmental history and international legal scholarship. From the Vietnam War to now, the international community has expanded wartime environmental protection language but hasn't turned those norms into accountability. The ILC's Draft Principles, advocacy for ecocide as an international crime, and growing environmental impact research all point to the same unresolved issue: international law acknowledges the environment's worth but hasn't shown the capacity to defend it during war. The future of wartime environmental protection depends on developing stronger legal principles and on enforcement bodies like the ICC and ICJ treating environmental destruction as a prosecutable crime, not just an unfortunate consequence of conflict.
