The United Nations marked the International Day of Peace on September 21 with calls for diplomacy and increased investment in peacebuilding efforts worldwide. Established in 1981, the annual observance aims to promote global ceasefires, non-violence, and conflict resolution. This year’s theme, "Invest in Peace – For Everyone, Everywhere, Every Day," underscored the need for sustained commitment to peace beyond symbolic observance.
UN Secretary-General Antonio Guterres reiterated these calls, urging world leaders to prioritize diplomacy over destruction and commended individuals contributing to peace efforts at the grassroots level. However, ongoing conflicts in several regions highlighted the persistent challenges facing the international community’s peacekeeping ambitions.
Despite a Security Council-endorsed ceasefire agreement in Gaza announced in October 2025, violence and restrictions persist, with civilians continuing to endure aerial attacks and humanitarian shortages amid stalled reconstruction efforts. Palestinians remain confined to shrinking territories, according to aid agencies, while Israel’s military operations and blockade conditions have not abated. The United States, which facilitated the resolution, has been criticized for limited action in ensuring enforcement.
Meanwhile, the war in Ukraine, now entering its fifth year, shows little sign of resolution. Russian forces maintain offensives in specific areas and continue drone attacks on civilian centers. Moscow has repeatedly vetoed Security Council resolutions that would impose limitations or condemnation, effectively stalling international efforts to address the conflict.
In addition, tensions involving Iran have escalated since early 2026, following US and Israeli strikes. These actions, occurring outside of Security Council authorization, sparked retaliatory incidents that have led to civilian casualties. Although investigations and fact-finding missions have been initiated, they have not succeeded in ending hostilities.
Critics argue that the Security Council’s repeated use of veto power by its five permanent members—the United States, Russia, China, France, and the United Kingdom—undermines the UN’s ability to act decisively in mass-casualty conflicts. The veto system, originally designed to prevent great power confrontation, often results in paralysis when major members’ interests are at stake, leaving vulnerable populations exposed.
Guterres acknowledged the systemic challenges in a recent interview, highlighting how the involvement of major powers in ongoing conflicts has eroded international law and stalled the Council’s peacekeeping role. He warned that escalating geopolitical divides contribute to impunity, encouraging states of middling power to act with increasing disregard for legal norms. The UN chief’s current term ends this December, and his successor will inherit an organization struggling to maintain relevance amid multiple crises.
Although the ongoing UN General Assembly continues to serve as a platform for leaders to express commitment to peace, the practical outcomes remain limited. Funding disputes, threats of withdrawal, and calls for reform have kept the UN functioning at a minimal level but have not addressed the core issue of veto power.
Observers contend that to move beyond rhetoric, the international community must confront the veto’s role in perpetuating conflict and hold members accountable to binding resolutions. Without such reforms, the International Day of Peace risks being little more than a symbolic reminder of the global system’s inability to prevent war. Meanwhile, conflicts in Gaza, Ukraine, and elsewhere continue to exact a heavy toll on civilian populations.
