The UN Security Council couldn’t stop Russia’s war against Ukraine

The need to reimagine its structure has never been greater.

The scene that played out at an emergency meeting of the United Nations Security Council on February 23, the day before Russia invaded Ukraine, was a devastating one. As the Ukrainian ambassador to the UN challenged the Russian ambassador about what his country was about to do, the moment was as poignant as it was pointless. The paralysis of the UN as a political body was painfully evident.

One increasingly evident flaw that prevents the UN from taking effective action in situations like this one is buried deep in its founding documents. The UN came into being in 1945, in the aftermath of World War II, with one central mission: maintaining international peace and security. The permanent members of the UN Security Council—the core group given sole responsibility for establishing peacekeeping operations, enacting international sanctions, and authorizing military actions—consisted of the five main powers that had just led the Allies to victory in the war: Great Britain, France, China, the United States, and the Soviet Union.

But this alliance had long been a fragile one, and at the Soviets’ insistence, each of these five countries was granted veto power over any Security Council resolution. When the Soviet Union collapsed in 1991, its membership was transferred—controversially—to the Russian Federation. This February the Security Council could only stand by helplessly while one of its permanent members used its veto power to violate the spirit and the letter of the council’s mission.
