Israel’s Strike on Iran: Examining the Role of International Law

On June 13, 2025, Israel launched strikes against Iran, reigniting discussions about the permissible use of force and the importance of national security. These actions, whether aimed at military targets or serving as retaliation, raise fundamental questions about international law, political legitimacy, and regional stability [[SOURCE]]. Israel defends its actions by citing the existential threat posed by Iran’s nuclear program, a justification that exists outside the legal framework established by the United Nations, signaling a move towards unilateralism.

The Legality of Israel’s Actions under International Law

International law, as enshrined in Article 2(4) of the UN Charter, prohibits the use of force, with two exceptions: self-defense in response to an armed attack (Article 51) and authorization by the Security Council. neither condition was met in the case of israel’s strike on Iran [[1]]. Iran had not directly attacked Israeli territory, and no UN resolution authorized the use of force against it.

Israel often invokes anticipatory self-defense, arguing that Iran’s nuclear capabilities pose an existential threat. However, this doctrine is controversial and not widely accepted in legal scholarship.It relies on the presumption of future aggression rather than an actual attack, deviating from the UN Charter’s strict legal framework. The 2003 U.S.invasion of Iraq, based on false claims of weapons of mass destruction, serves as a cautionary tale of the dangers of misapplying such logic.

Did You Know? The International Atomic Energy Agency (IAEA) plays a crucial role in monitoring Iran’s nuclear program, but military action disrupts these diplomatic mechanisms.

Moreover, the Israeli strike violates Iranian sovereignty, protected under customary international law. According to UN General Assembly Resolution 3314 (1974), such an act might potentially be classified as aggression, especially without security council endorsement. This undermines international institutions and weakens the rule of law [[2]].

Strategic Implications and Regional Stability

Israel presents its attack as necessary to prevent Iran from acquiring nuclear weapons, framing the mere capability of an adversary as an intolerable risk. While concerns about a nuclear-armed Iran are widespread, the legitimacy of a preemptive strike depends on proportionality and imminence. Iran has enriched uranium beyond the 60% threshold, but it has not built a nuclear bomb, and the IAEA has not confirmed any intent to weaponize. Therefore,Israel’s strike is based more on projected intent than concrete evidence of an imminent threat.

Strategically,the strike could be counterproductive,potentially strengthening Iranian hardliners and undermining moderates who advocate for negotiation.It may also prompt Iran to accelerate its nuclear ambitions, demonstrating that diplomacy offers no protection from foreign aggression. Moreover, it weakens regional and international mechanisms designed to contain such crises through dialogue and oversight.

pro Tip: Consider the broader geopolitical landscape. Israel’s strike signals strategic unilateralism, testing the limits of U.S. support, the patience of Gulf countries, and the effectiveness of international non-proliferation frameworks.

The Broader Impact on international Norms

By acting without UN authorization, Israel reinforces a pattern where states bypass legal frameworks under the guise of national security, eroding collective security systems. This reflects a deeper crisis of multilateralism, where the UN security Council is often paralyzed by great-power rivalry. Countries increasingly act unilaterally, justifying force as a defensive measure, even when the threat is speculative.

Such precedents are consequential. Other regional powers may feel emboldened to use force preemptively, citing national interest or perceived threats. The more these practices go unchecked, the more fragile international norms become. Israel’s actions could accelerate a global shift toward a security paradigm governed by ad hoc coalitions and individual calculations rather than international law.

while Israel’s concerns about Iran are not unfounded, resorting to military action outside legal channels compromises the foundations of a stable international order. It promotes a system where might determines right, and where the legitimacy of action is judged solely by its effectiveness, not by its legality or broader impact. In the long term, this approach is unsustainable.

The Risky Precedent Set by the Israeli Strike

The Israeli strike on Iran sets a dangerous precedent, both legally and strategically. by acting outside international law, Israel undermines core principles of sovereignty and multilateral governance. Its reliance on contested doctrines of anticipatory self-defense weakens the prohibition on the use of force and invites other states to adopt similar justifications. Strategically, the action risks deepening regional instability, reinforcing hardline factions in Iran, and delegitimizing international oversight institutions.

At stake is more than a bilateral dispute between Israel and Iran. This strike represents a broader assault on the norms and institutions that underpin global peace and security. The international community must respond through concrete efforts to reassert the primacy of law over force. Without such a response, the world risks descending into a new era of strategic unilateralism.

Key Considerations

• The principle of anticipatory self-defense is controversial and not widely accepted in legal scholarship.
• The IAEA’s role in monitoring iran’s nuclear program is central to diplomacy.
• Israel’s strike signals strategic unilateralism, testing the limits of U.S. support and the effectiveness of international non-proliferation frameworks.
