Ukrainian President Volodymyr Zelensky expressed concern over the lack of advance warning from the United States and other allies before a Russian ballistic missile attack that occurred on Sunday night. Zelensky noted that this incident marked the third time in a short span that Ukraine had not received its usual early warnings of ballistic missile threats, raising questions about the reliability of intelligence sharing.
In response to these concerns, U.S. President Donald Trump dismissed claims that intelligence sharing with Ukraine had ceased, insisting that the United States continues to provide necessary intelligence. Despite this, Ukrainian officials are suspicious that the U.S. may have temporarily withheld intelligence, which might have led to the initial wave of Russian attacks proceeding without warning. They assert that early-warning support resumed before a subsequent wave of strikes later that night.
A U.S. Defense Department official countered these suspicions, stating that there has been no change in the Pentagon’s policy on intelligence sharing with Ukraine. This dispute over intelligence sharing occurs amid broader tensions between Zelensky and Trump regarding the ongoing war and the efforts to bring it to an end.
In March 2025, a temporary suspension of intelligence sharing occurred following a heated meeting involving Zelensky, Trump, and U.S. Vice President JD Vance. Although that suspension was eventually lifted, the current situation highlights ongoing challenges in the collaboration between the U.S. and Ukraine.
