’Our task now is to do everything we can to ensure that Putin is left with no other path’

On June 3, the opening day of the St. Petersburg International Economic Forum, Ukrainian drones struck the city. On June 4, Volodymyr Zelensky published an open letter to Vladimir Putin calling for a face-to-face meeting and an end to the war. The letter’s tone, however, was more combative than conciliatory. Putin declined to meet.

Sources in the Verkhovna Rada who spoke with the news outlet Ukrainska Pravda (UP) said the drones and the letter are part of a broader Ukrainian “military-diplomatic campaign” designed to convince Putin that there is no alternative to “serious negotiations.”

“Putin shows no sign of wanting to move quickly toward negotiations. But there are many indirect signals and hints from major world powers that by fall the situation could change in a way that gives him no choice. Our task now is to do everything we can to ensure that Putin is left with no other path,” a source in Zelensky’s office told UP.

’Wait until July and you will see what Ukrainian strength is’

After the U.S.–Iran war broke out, Russian–Ukrainian peace talks mediated by the Trump administration stalled. “We have to acknowledge the obvious: the previous negotiating process is all but dead. It’s frozen and going nowhere,” a member of Zelensky’s diplomatic team told UP.

Ukraine’s presidential office is working to refocus American attention on negotiations, engage European governments in the process, and consolidate its own bargaining position. Kyiv sees its advantages as the escalation of long-range strikes on Russia, the denial of Starlink satellite communications to Russian forces, and a breakthrough in medium-range drones.

The last of these has already turned the Rostov-Simferopol highway into a “road of death” and triggered a fuel crisis in Crimea. The Ukrainian military’s goal is an “operational drone blockade” that would sever the land corridor to the annexed peninsula. According to UP’s sources in the Ukrainian military high command, that process is already underway. “Wait until July and you will see what Ukrainian strength is,” one of them said, without elaborating.

Planning for the October–November ‘window of opportunity for talks’

Zelensky has also intensified his public pressure campaign, sending two messages to Putin: one relayed privately through billionaire Roman Abramovich, and another posted publicly on Zelensky’s official website.

Abramovich had tried to broker talks between Russia and Ukraine in 2022. In May 2026, he traveled to Kyiv and met with Zelensky. According to the Ukrainian president, Abramovich wanted to find out what compromises Kyiv was prepared to make in peace negotiations. Zelensky replied that Ukraine had no intention of ceding Donbas to Russia. Zelensky also told Abramovich that he was proposing a direct meeting with Putin. UP reports that Zelensky’s message was accompanied by an “addendum” from Ukraine’s negotiating team. The outlet described its substance as follows: Russian military commanders are misleading Putin about the true situation at the front; they won’t capture all of Donbas — not by late summer or fall. And when Putin realizes Ukraine warned him, he should stand down and come to the table.

Zelensky’s open letter to Putin also called for a face-to-face meeting and negotiations. But its main goal was to press Russia on Ukraine’s terms and recapture international attention. Zelensky’s office did not expect Putin to agree on the spot.

“Nobody at Bankova [Ukraine’s presidential administration] was counting on Putin agreeing to end the war in June or July. But another date keeps surfacing in conversations with Ukrainian officials — October–November,” UP reports, citing a source from Zelensky’s diplomatic team: “That’s when everything comes together — all the military, diplomatic, and international factors — and a window of opportunity for talks might open. Somewhere before the American elections and after the Russian Duma elections.”

Members of Zelensky’s team believe that by late fall, there will be a chance to “lock in the new balance of forces on the battlefield, at least through diplomatic means,” and secure a phased end to the fighting. Ukraine’s leadership plans to use the remaining months to strengthen its military and diplomatic hand before any talks begin.
