US intelligence sharing with Ukraine rebounds to previous highs

The intelligence-sharing relationship between the U.S. and Ukraine has bounced back to previous highs, according to long-time Ukraine watchers — a welcome boost during a critical window of opportunity for the Ukrainian war effort.

Sen. Mark Warner (D-Va.), the intelligence committee’s ranking member and a longtime proponent of more U.S. assistance to Ukraine, told POLITICO he sees evidence of an improved intel-sharing agreement — and believes it’s helped Kyiv gain an advantage in Moscow’s four-year-long war.

“I don’t want to get into any specifics, but it has improved,” he said, adding that Ukraine’s use of long-range drones and missiles has allowed it to strike deep within Russian territory and strengthen its position.

In recent months, Kyiv has carried out more aggressive strikes across Russia, enabling it to take back territory and stabilize the front line. This has afforded the country more leverage as Ukraine looks to parlay battlefield wins to pressure Russia to the negotiating table.

Ukraine’s stronger footing also comes as U.S.-mediated talks to strike a peace deal 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.

But in that time, Ukrainian President Volodymyr Zelenskyy appears to have risen in President Donald Trump’s estimation as Kyiv has made gains against Russia.

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 . The increased frequency of those kinds of targeted attacks has put the Kremlin in a tighter spot, creating what Kyiv has argued is a window of opportunity for Ukraine to leverage its current advantage to end the war.

Republican Sens. John Cornyn (R-Texas), another member of the intel committee, and Roger Wicker (R-Miss.), who chairs the Senate Armed Services Committee, agreed that intel-sharing between the U.S. and Ukraine has increased at a moment of strategic importance.

“It sure seems like that,” Cornyn said. “Everybody loves a winner and looks like Ukraine has turned the tide.”

Sen. Tim Kaine (D-Va.), a Democratic armed services committee member, told POLITICO he’s also seen signs of greater communication between Ukraine and the U.S.

“I was in Ukraine in April 2025 and I was there again in July 2026. 
And I detect more confidence in the communication,” Kaine said.

Cooperation from the U.S. has been key to Ukraine’s positive turn in fortune, said George Barros, the director of innovation and open source tradecraft at the hawkish Institute for the Study of War. Trump reportedly approved intelligence sharing for Ukrainian strikes on Russian energy infrastructure last year, which have been essential to creating a “proper incentive structure” to push Moscow to the negotiating table, Barros noted.

The strikes, he said, were “supercharged,” and became significantly more effective when imbued with intelligence from the Americans, part of a “larger, more coherent strategy for how to actually create real costs.”

And American early warning systems, Barros added, have been alerting Ukrainians to incoming Russian missile attacks since the early days of the war.

The White House did not provide details on whether its intelligence-sharing relationship with Ukraine has expanded, though it stressed that Trump is focused on facilitating an end to the war.

“The President wants this war settled so the senseless killing ends,” said the White House spokesperson 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 a request for comment.

Washington also stands to benefit from Kyiv’s intelligence, said John Herbst , who served as U.S. ambassador to Ukraine from 2003-2006 and still maintains contact with officials in the country.

“There’s no doubt of the following: Ukraine has outstanding intelligence on Russia,” he said.

Zelenskyy has sought to put that intelligence to use . With Washington locked in a five-month war against Iran, the Ukrainian president prefaced his July visit to the Oval Office by claiming Kyiv planned to provide Trump with evidence that Russia was aiding Tehran.

“When you talk to Ukrainian intelligence officials, you hear confident insights into what is going on in Moscow, and not just in the Kremlin,” said Stephen Sestanovich, a fellow for Russian and Eurasian Studies at the Council on Foreign Relations. “Insights of a sort that justify a truly cooperative and reciprocal sharing arrangement.”
