On Thursday night, Zavadska had a terrible feeling but couldn’t explain why. She hugged Khudia tight for 10 minutes and told him to update her every hour until he went to sleep.Air sirens blared at 1 a.m., and she texted him to ask if everything was OK. There was no reply. She waited out the alert in a nearby basement.

In the morning, Khudia’s best friend called. Khudia’s house had been hit by a Russian missile. His remains had been found. He had died instantly. His parents were also killed. His sister was pulled from the rubble alive.Friends of Danylo Khudia, 17, who was killed on Thursday by a Russian strike, gather near the rubble of a house in a residential neighborhood in Kyiv, Ukraine, on Friday, April 25, 2025.

Whether the U.S. formally recognizes Crimea as Russian is out of Zelenskyy’s hands. But many obstacles prevent the Ukrainian president from doing so, even under immense pressure. He cannot unilaterally sign any such proposal, and he could be reprimanded by future governments for even attempting it, experts said.Ukraine began to accept that it would not regain its lost territories after the

. From then on, the Ukrainian military concentrated on defending the territory it still held.In return for territorial concessions, Ukraine wants robust security guarantees that ideally would include NATO membership or concrete plans to arm and train its forces against any future Russian invasion with the pledged support of allies.
