The war with Iran has starkly illustrated the diminishing relevance of international organizations, particularly the United Nations (UN) and the European Union (EU), in managing global conflicts. The UN Security Council, designed to uphold international peace, has been rendered ineffective due to the veto powers of its permanent members, notably during the US-Israeli military actions against Iran in February 2026. A resolution passed on March 11 condemned Iran's actions but failed to address the initial strikes that escalated the conflict, showcasing the Council's double standards. Meanwhile, the EU, which once played a crucial role in negotiating the Iran nuclear deal, has found itself sidelined, unable to present a unified response to the crisis. This fragmentation among member states, coupled with a dependency on the US for security, has diminished the EU's capacity to act decisively. Despite these challenges, the potential for revitalizing multilateralism exists through mechanisms like the Uniting for Peace procedure within the UN. The need for political will to leverage these resources and restore the credibility of international organizations is critical to overcoming the current geopolitical crisis.
