Mark Warner, the senior Democrat on the Senate Intelligence Committee, said intelligence sharing between the United States and Ukraine had returned to previous levels and that the cooperation was affecting Kyiv’s operations deep inside Russian territory.
Warner did not disclose details of the intelligence sharing but said the cooperation had improved. He said Ukraine had expanded its attacks deeper into Russia using long-range unmanned aerial vehicles and missiles, adding that this had strengthened Kyiv’s position.
Intelligence sharing was suspended in February 2025
The U.S. administration temporarily suspended intelligence sharing with Kyiv after a tense meeting between Ukrainian President Volodymyr Zelenskyy and senior U.S. officials in the Oval Office in February 2025.
Two Republican senators said intelligence cooperation had expanded at a critical time. Texas Senator John Cornyn said developments appeared to be moving in that direction and argued that Ukraine was changing the course of the war.
Virginia Senator Tim Kaine said he had observed a higher level of trust in communication between the parties during his visits to Ukraine.
The role of U.S. intelligence in Ukraine’s defense
George Barros of the Institute for the Study of War said U.S. intelligence had played a significant role in Ukraine’s recent successes. Barros said intelligence support approved by U.S. President Donald Trump for attacks on Russia’s energy infrastructure had increased the effectiveness of the operations.
Barros said the support was part of a broader strategy aimed at putting negotiating pressure on Moscow. He also said U.S. early-warning systems had helped Ukraine defend against Russian missile attacks throughout the war.
