A showdown over Ukraine between the United States and its longtime European allies played out in the United Nations on Monday, as the United States opposed an effort to condemn Russian aggression and call for the immediate withdrawal of Russian forces from Ukraine.

After losing a vote on Ukraine in the U.N. General Assembly, the United States won approval in the U.N. Security Council for its own resolution calling for an immediate peace, without mentioning the Russian invasion of Ukraine or assigning any blame. Security Council resolutions, though sometimes flouted, are considered legally binding, giving added weight to President Trump’s push to negotiate an end to the war.

In both the General Assembly and the Security Council, the United States and some of its closest allies, including Britain and France, were in opposing camps on Monday, a remarkable public fissure between countries that have typically stood together when it comes to Russia and Europe’s security. Coming on the third anniversary of Russia’s full-scale invasion of Ukraine, it demonstrated the sharp turn in U.S. foreign policy under President Trump.

The U.S. “resolution puts us to the path to peace,” said Dorothy Camille Shea, the interim chargé d’affaires representing the United States, after the Security Council vote. “Now we must use it to build a peaceful future for Ukraine, Russia and the international community.”

But Britain’s ambassador, Barbara Woodward, in explaining its opposition to the measure, said: “The terms of the peace must send a message that aggression does not pay. This is why there can be no equivalence between Russia and Ukraine in how this council refers to the war.”

The face-off at the United Nations began with a three-page resolution introduced by Ukraine, demanding Russian withdrawal, calling for a “comprehensive, lasting and just peace,” and for accountability for Russia’s war crimes.
