Intelligence cooperation between the United States and Ukraine has returned to peak levels, according to senior lawmakers and defense analysts, providing Kyiv with critical advantages as Moscow's four-year war grinds on with no peace deal in sight.
Sen. Mark Warner, D-Va., the intelligence committee's ranking member, confirmed the enhanced relationship has helped Ukraine gain ground against Russian forces. "I don't want to get into any specifics, but it has improved," Warner said. He credited Ukraine's use of long-range drones and missiles with enabling strikes deep within Russian territory, strengthening Kyiv's negotiating position.
Battlefield Gains Shift Momentum
Kyiv's more aggressive strike campaign across Russia in recent months has allowed it to reclaim territory and stabilize front lines. The improved battlefield position gives Ukraine leverage as it seeks to pressure Moscow toward negotiations. Republican Sens. John Cornyn of Texas and Roger Wicker, who chairs the Senate Armed Services Committee, both acknowledged the intelligence-sharing increase comes at a strategically important moment. "It sure seems like that. Everybody loves a winner and looks like Ukraine has turned the tide," Cornyn said.
Sen. Tim Kaine, D-Va., who visited Ukraine in April 2025 and again in July 2026, said he's detected greater confidence in U.S.-Ukrainian communication. "I detect more confidence in the communication," Kaine said.
George Barros, director of innovation and open source tradecraft at the Institute for the Study of War, said American cooperation has been essential to Ukraine's recent success. Trump reportedly approved intelligence sharing for Ukrainian strikes on Russian energy infrastructure last year. Those strikes became "supercharged" and significantly more effective when paired with U.S. intelligence, Barros said, part of a "larger, more coherent strategy for how to actually create real costs." American early warning systems have been alerting Ukrainians to incoming Russian missile attacks since the war's early days, he added.
Strategic Value Flows Both Ways
The intelligence relationship isn't one-sided. John Herbst, who served as U.S. ambassador to Ukraine from 2003-2006 and maintains contact with Ukrainian officials, said Washington benefits from Kyiv's insights. "There's no doubt of the following: Ukraine has outstanding intelligence on Russia," he said.
Stephen Sestanovich, a fellow for Russian and Eurasian Studies at the Council on Foreign Relations, said Ukrainian intelligence officials offer "confident insights into what is going on in Moscow, and not just in the Kremlin." He called them "insights of a sort that justify a truly cooperative and reciprocal sharing arrangement."
In early July, a barrage of Ukrainian strikes on Russian energy infrastructure forced Moscow, one of the world's top fuel exporters, to halt its exports of diesel. Ukrainian President Volodymyr Zelenskyy has sought to leverage that intelligence, claiming before his July visit to the Oval Office that Kyiv planned to provide Trump with evidence that Russia was aiding Tehran.
Peace Talks Stalled as Priorities Shift
Ukraine's stronger footing comes as U.S.-mediated peace talks with Moscow have stalled. Trump's negotiating team, which includes Steve Witkoff and Jared Kushner, has been preoccupied with the Iran war, bumping Ukraine down its priority list. Zelenskyy appears to have risen in President Donald Trump's estimation as Kyiv has made gains against Russia.
The White House did not provide details on whether its intelligence-sharing relationship with Ukraine has expanded. "The President wants this war settled so the senseless killing ends," a White House spokesperson said in a statement. "The President and his team remain committed to continuing to play a constructive role in ending the war between Russia and Ukraine, and he remains optimistic that we'll ultimately get a peace deal done." The CIA and ODNI did not respond to requests for comment.
Why This Matters:
The enhanced intelligence partnership demonstrates how strategic cooperation can shift battlefield dynamics without massive troop deployments or open-ended financial commitments. Ukraine's ability to strike Russian energy infrastructure and military targets deep inside Russia creates real costs for Moscow's war machine, potentially forcing Putin to reconsider the conflict's sustainability. For American taxpayers, intelligence sharing represents a relatively cost-effective investment compared to direct military intervention. The reciprocal nature of the relationship also serves U.S. national security interests, providing Washington with valuable insights into Russian military capabilities, decision-making processes, and potential connections to adversaries like Iran. As peace negotiations remain stalled, Ukraine's improved position on the ground may prove essential to securing terms that don't reward Russian aggression or undermine deterrence against future conflicts.
