On a Monday morning last fall, Ukrainian drone pilots watched what had become a familiar scene unfold on a drone’s live feed: Russian soldiers pointed their guns at two Ukrainians, who seemingly surrendered. Then, the footage showed, the Russians shot them point blank.

The video, provided by a pilot who said he had witnessed the killing on the feed, was verified by The New York Times and the Centre for Information Resilience, a nonprofit organization. It appeared to show the Ukrainian prisoners executed near the village of Novoivanovka in the Kursk region of Russia.

“There were no polite words spoken among us — we were filled with rage and an intense desire for revenge,” said the pilot, 26, who served with the 15th Mobile Border Guard and asked to be identified by his call sign of “One Two” in accordance with military protocol.

As the United States embraces Russian talking points in its push for a cease-fire in Ukraine, many Ukrainians wonder whether allegations of Russian war crimes will simply be forgotten. President Trump has indicated that he would like to re-establish ties with Russia and end the war — or at least, wind down the U.S. commitment to Ukraine made under President Joseph R. Biden Jr.

The U.S. informed European officials recently that it is withdrawing from a multinational group created to investigate allegations of war crimes against senior Russian leaders and allies responsible for launching the full-scale invasion of Ukraine in 2022. The Biden administration joined the group in 2023. The U.S. State Department has also ended funding for the tracking of tens of thousands of Ukrainian children abducted by Russia.

While both sides have been accused of committing war crimes, Russia has faced far more allegations, not only from Ukraine but also human-rights groups and the United Nations. In recent months, Ukrainian and international human-rights officials have accused Russian troops of executing Ukrainian soldiers who have surrendered instead of taking them as prisoners of war, as required under the Geneva Conventions treaties that outline how nations should treat enemy forces and civilians during armed conflict.
