International Law Explained: How Trump's New World Order Sidelines UN Charter
The recent joint US-Israeli military strikes against Iran have sparked a fundamental crisis in international law, with experts warning that President Trump's emerging 'new world order' threatens to sideline the United Nations Charter and established global legal frameworks. According to international law scholars, the attacks violate the UN Charter's prohibition on aggression and represent a dangerous erosion of the post-World War II international legal system.
What is International Law and Why Does It Matter?
International law refers to the system of rules and principles governing relations between sovereign states, established primarily through treaties, customs, and international agreements. The cornerstone of modern international law is the United Nations Charter, adopted in 1945, which prohibits the use of force except in two specific circumstances: when authorized by the UN Security Council or in self-defense against an armed attack. This framework was designed to prevent the kind of unilateral aggression that led to World War II and has maintained relative global stability for nearly eight decades.
The Legal Violations: US-Israeli Attacks on Iran
According to international law experts, the recent strikes against Iran constitute clear violations of the UN Charter. 'America and Israel have attacked the cornerstone of the international legal order, namely the prohibition on the use of force,' says Marieke de Hoon, associate professor of international law. 'That prohibits an attack on the sovereignty and territorial integrity of Iran.'
Why These Attacks Violate International Law
The legal violations center on three key principles:
- No UN Security Council Authorization: The attacks lacked authorization from the UN Security Council, where any of the five permanent members (US, Russia, China, UK, France) can veto resolutions.
- No Valid Self-Defense Claim: International law experts argue Iran had not launched an armed attack against the US or Israel, nor was there an 'instant, overwhelming' threat justifying preemptive action.
- Violation of Sovereignty: The strikes violated Iran's territorial integrity, a fundamental principle of international law since the 1648 Peace of Westphalia.
Larissa van den Herik, professor of international law, emphasizes: 'Only with permission from the UN Security Council or in case of a direct threat may countries attack each other. And according to her, the claim of self-defense by the US and Israel does not hold up.'
The UN Security Council Veto Problem
The current crisis highlights a fundamental flaw in the international legal system: the UN Security Council veto power. The five permanent members (P5) can block any substantive resolution, effectively paralyzing the UN's ability to respond to conflicts involving major powers or their allies. This has been particularly evident in recent years with Russia vetoing resolutions on Ukraine and the US blocking ceasefire calls in Gaza.
The veto system, established in 1945 to ensure great power cooperation, has increasingly become a tool for geopolitical obstruction. As the UN Security Council reform debates continue, many experts argue the current structure makes the organization 'practically wingless' in addressing contemporary conflicts.
Trump's Alternative: The Peace Council
President Trump has responded to UN paralysis by creating an alternative international body: the Board of Peace (often called the Peace Council). Launched in January 2026, this organization represents Trump's vision for a 'new world order' that operates outside traditional UN frameworks. While originally presented as implementing a Gaza peace plan, leaked documents reveal ambitions to become a global decision-making body.
The Peace Council's structure grants Trump extensive powers as chair, including authority to appoint and remove member states. With participation mainly from autocratic nations and limited European support (only Hungary and Bulgaria from the EU), the council represents a significant challenge to the UN's authority. This development follows Trump's withdrawal of the US from over 60 international organizations in December 2025, signaling a broader rejection of multilateral institutions.
The Double Standard Dilemma
International law experts warn that selective enforcement creates dangerous precedents. 'When Trump threatened to annex Greenland, Western countries closed ranks against his plan and were full of talk about territorial integrity,' notes De Hoon. 'That was very hopeful. But a few weeks later in the case of Iran, that all seems not to matter anymore.'
This perceived double standard particularly affects non-Western nations, who increasingly question whether international law applies equally to all states. The situation echoes concerns about the ICC investigations of world leaders and whether powerful nations face different standards than weaker states.
What Happens When International Law Fails?
The erosion of international legal constraints has serious implications for global stability. Van den Herik warns: 'If we now agree that international law no longer matters, then we give Trump, Russia and China a free pass to do what they are already doing.'
Potential consequences include:
- Increased unilateral military interventions by powerful states
- Weakening of diplomatic conflict resolution mechanisms
- Accelerated arms races and regional instability
- Erosion of human rights protections and humanitarian law
Despite these challenges, some experts remain hopeful. Van den Herik advocates that 'the Netherlands and Europe should stand together with other countries around the United Nations' to support the organization and international law as much as possible.
Frequently Asked Questions
What is the UN Charter's prohibition on the use of force?
The UN Charter Article 2(4) prohibits the threat or use of force against the territorial integrity or political independence of any state, with exceptions only for Security Council authorization or self-defense against armed attack.
Can countries attack others to prevent future threats?
International law allows preemptive self-defense only against an 'instant, overwhelming' threat leaving no choice of means. Hypothetical future threats don't justify unilateral military action.
What is Trump's Peace Council?
The Board of Peace is an alternative international organization created by President Trump in 2026, originally as part of a Gaza peace plan but evolving into a potential rival to the UN with Trump as chair and extensive powers.
Why does the UN Security Council have veto power?
The veto power for five permanent members (US, Russia, China, UK, France) was established in 1945 to ensure great power cooperation and prevent the UN from taking action against major powers without their consent.
What happens if international law collapses?
Without functioning international law, the world risks returning to a system where 'might makes right,' with powerful states acting unilaterally and weaker states vulnerable to aggression without legal protection.
