War, Law, and Global Order: Understanding the Iran-Israel-USA Conflict
The world stands at a critical moment. In late February 2026, what had long been simmering tensions between Iran, Israel, and the United States erupted into a full-blown military confrontation what many are calling one of the most serious wars in the Middle East in decades.
What Happened? A Brief Overview of the Conflict
On 28 February 2026, the United States and Israel launched coordinated military strikes on Iran in a campaign known in U.S. planning as Operation Epic Fury and in Israeli statements as Operation Lion’s Roar. The strikes targeted Iranian military facilities, command centres, missile infrastructure, and reportedly the leadership of Iran’s government, including Supreme Leader Ayatollah Ali Khamenei.
Iran responded with a massive wave of missile and drone attacks against Israeli cities and U.S. military bases across the Gulf states. Iran’s strategic allies, notably Hezbollah in southern Lebanon, have since joined the conflict by firing rockets into Israeli territory, prompting Israeli strikes on Lebanese regions.
The situation has quickly grown beyond a bilateral engagement, spreading disruption across the Strait of Hormuz, shaking global oil markets, prompting diplomatic condemnations, and threatening wider instability across the Middle East and beyond.
The Legal Battlefield: War and International Law
The violence raises some of the most fundamental questions about international law — questions that go beyond politics:
1. The UN Charter and the Use of Force
Under the United Nations Charter, all member states must refrain from the threat or use of force against the territorial integrity or political independence of other states. Force is lawful only in two cases:
If a state is acting in self-defence after an armed attack, or
If the UN Security Council authorises the use of force as necessary to maintain or restore international peace and security.
The U.S. and Israeli governments have justified their actions by claiming they were pre-emptive and defensive against an “existential threat.” But pre-emptive force is not clearly authorised under current international law unless an armed attack is imminent. Many legal scholars argue that such unilateral strikes without UN authorisation stretch or break the legal norms meant to govern state use of force.
The International Commission of Jurists has publicly called the attacks a grave violation of the UN Charter and international law, stating that the actions threaten peace and civilian protection.
2. Responsibility to Protect Civilians
Even in armed conflict, states must protect civilians and limit attacks to military objectives under international humanitarian law (IHL) the law of war. This includes:
Avoiding indiscriminate attacks,
Taking all feasible precautions to spare civilians,
Not targeting hospitals, schools, and civilian infrastructure.
Reports indicate that civilian areas including a school in Minab, southern Iran were struck, causing significant loss of life. The legality of such strikes is highly contested, given the humanitarian principles at stake.
3. Self-Defence or Regime Change?
International law allows defensive war, not regime change. If the core goal of the military operations is to overthrow Iran’s government or assassinate its leadership, as some reports suggest, then such actions may amount to illegal aggression under the legal framework that the UN system is built on.
Voices from Around the World
The international reaction has been polarised:
Some governments have condemned the strikes as unlawful and destabilising.
Others have expressed support for efforts to counter what they see as a threat.
The UN Secretary-General and many legal experts are calling for restraint and for all parties to honour their legal obligations to protect civilians and pursue peace.
This moment underscores a grim reality: when law collapses under the weight of force, it is ordinary people not politicians who bear the cost.
Why This Matters
War between powerful states isn’t just about bombs and missiles it’s about the rules that govern global order. When those rules are set aside, the consequences ripple across borders: from legal norms that protect nations to economic markets that depend on regional stability, and to millions of lives disrupted by violence.
Civil society, legal institutions, and governments must now ask fundamental questions:
When is it lawful to go to war?
What protections do civilians have under law?
Can diplomacy and international institutions still prevent or end war?
If international law is to survive the conflicts of the 21st century, these questions must be answered not just by lawyers and diplomats but by citizens around the world.
