What is International DiploMUN Online?
What Is a Model United Nations (MUN) Conference?
Model United Nations (MUN) conferences are internationally recognized academic simulations where students represent real-world countries and defend their interests in global debates. Participants — ranging from middle school to university level — take on the role of diplomats in bodies such as the UN Security Council or General Assembly. By negotiating resolutions to global crises, they develop highly sought-after 21st-century skills such as leadership, oratory, negotiation, and strategic thinking. More than just a competition, MUN is a gateway to global citizenship and a powerful platform for those aspiring to careers in diplomacy, international relations, law, business, or public policy.

This year, our priority is to reduce the size of IDO while dramatically raising the bar of competitiveness and rigor. Expect tighter committee caps, harder topics, faster-paced procedure, and stricter evaluation. Seats are limited, selection will weigh clarity of motivation and prior engagement, and awards will be reserved for exceptional performance in research depth, bloc leadership, clause craftsmanship, and live negotiation. In short: fewer slots, much higher level — an extremely competitive conference designed to make you sharper, faster, and truly ready for HMUN/HNMUN and ILMUNC.

Committee & Topic
Social, Humanitarian, and Cultural Committee – “Never Again”—Again? — Ethnic Cleansing & Present-Day Genocides
Despite global promises of “Never Again,” the 21st century continues to witness mass atrocities that echo the darkest chapters of human history. From the Rohingya crisis in Myanmar to the persecution of Uyghurs in China, from the Tigray conflict in Ethiopia to escalating communal violence in regions of the Middle East and Eastern Europe—the mechanisms of ethnic cleansing have evolved, but the international response remains painfully familiar: statements of condemnation, delayed action, and political deadlock.
In this committee, delegates will confront one of the most complex dilemmas in international relations: When does political neutrality become complicity? Nations are often reluctant to label ongoing crises as genocide due to legal and diplomatic consequences, while powerful states leverage humanitarian narratives for strategic gain. Delegates must navigate competing definitions, conflicting intelligence, media manipulation, and the geopolitics surrounding intervention. Is military intervention ever justified? Should economic sanctions or international tribunals be the primary response? And what responsibility—if any—do corporations and social media platforms bear in these crises?
This committee will also examine the early warning signs of genocide, from hate speech and forced displacement to cultural erasure and digital surveillance. Delegates will be tasked not only with responding to active humanitarian emergencies but also with designing proactive international frameworks capable of detecting and preventing ethnic cleansing before it escalates. Collaboration with NGOs, peacekeeping operations, and judicial bodies such as the International Criminal Court will be crucial in crafting realistic and enforceable resolutions.
Ultimately, this is not just a historical debate — it is a test of political courage. Delegates must determine whether “Never Again” will remain a hollow slogan repeated after every tragedy, or whether today’s leaders will establish the structures necessary to prevent the next one. The world has heard the promise. In this committee, it is time to decide whether we will finally keep it.
