Three weeks after their much-publicized but ultimately inconclusive summit in Alaska, U.S. President Donald Trump and Russian President Vladimir Putin have shifted the spotlight back to Europe in the ongoing search for a path to peace in Ukraine. The two leaders, who have repeatedly exchanged both public barbs and diplomatic overtures, are now singling out Europe as the key player whose actions—or inactions—could determine the fate of peace negotiations.
On September 3, 2025, President Trump sat in the Oval Office, fielding questions about the deadlock in Ukraine. According to CNN, he offered little clarity on whether the U.S. would impose direct sanctions on Russia if Putin failed to meet yet another two-week deadline for progress in the peace process, a deadline that expired on September 5. Instead, Trump hinted at further action, saying, “Whatever his decision is, we’ll either be happy about it, or unhappy. And if we’re unhappy about it, you’ll see things happen.”
The following day, Trump picked up the phone for a round of calls with European leaders, as well as Ukrainian President Volodymyr Zelensky. The focus of those conversations? Economic pressure on Russia and the urgent need to cut off the financial lifelines fueling its war machine. As reported by the White House, Trump emphasized that “Europe must stop purchasing Russian oil that is funding the war—as Russia received €1.1 billion in fuel sales from the EU in one year.” He also urged European leaders to ramp up economic pressure on China, which the U.S. accuses of helping finance Russia’s war efforts.
For his part, Zelensky was blunt in his assessment of the situation. He told European and American officials that Russia would not sign a peace treaty without suffering a military defeat, and he called for intensified international pressure on Moscow. “Depriving Russia’s war machine of money” was the phrase he used to describe the strategy, according to CNN.
Meanwhile, European countries have been steadily reducing their dependence on Russian energy. Member states have imposed bans on maritime oil exports and refined oil products, causing Russian oil imports to Europe to plummet from $16.4 billion in the first quarter of 2021 to just $1.72 billion in the same period of 2025. This shift, while significant, has not been enough to satisfy Washington’s demands for a total cutoff.
Putin, not to be outdone in the blame game, has accused Europe of obstructing dialogue between Moscow and Washington. In a meeting with Chinese leaders, he insisted that Europe “should not throw a wrench in the works” of U.S.-Russian diplomacy. He also reiterated Moscow’s firm opposition to the deployment of foreign troops in Ukraine as part of any peace agreement. Russian Foreign Ministry spokeswoman Maria Zakharova echoed this stance, calling the idea of foreign troops “unacceptable.”
All the while, Russia has been intensifying its efforts to sow discord among NATO allies. According to CNN, Putin’s recent meetings with Chinese and Slovak leaders included accusations that Europe was whipping up “hysteria” over supposed Russian threats. “Any sane person is perfectly aware that Russia has never had, does not have, and will never have any desire to attack anyone,” Putin declared—a statement that rang hollow for many, given Russia’s invasions of Ukraine in 2014 and 2022.
The diplomatic maneuvering has not been limited to the U.S. and Russia. On September 2, Finland’s President Alexander Stubb told Reuters that progress was being made on security guarantees for Ukraine, but he cautioned that these could only be implemented once a peace agreement was in place. “We need to coordinate the security arrangements with the United States, which essentially will provide the backstop for this,” Stubb said. He noted ongoing efforts with defense chiefs to draw up concrete plans, adding, “We’re making progress on this and hopefully we’ll get a solution soon.” Still, Stubb admitted he was not optimistic about a near-term peace agreement or ceasefire between Ukraine and Russia.
Stubb was among several European leaders who traveled to Washington in August for a joint meeting with Trump and Zelensky. The goal: to discuss prospects for peace and coordinate security guarantees that might one day underpin a ceasefire. The United States, for its part, is considering a limited role in these guarantees, wary of overcommitting while still signaling support for Ukraine’s sovereignty.
French President Emmanuel Macron added another layer to the evolving security landscape. After a call with Trump, Zelensky, and other leaders of the so-called “Coalition of the Willing” on September 4, Macron announced that 26 countries had pledged to fund a potential peacekeeping force if a ceasefire is reached. “Alongside strengthening Ukraine’s armed forces and deploying European troops to Ukraine, the third component of Ukraine’s security guarantees ought to be an ‘American safety net,’” Macron said, according to CNN.
Despite these glimmers of progress, the peace process remains mired in uncertainty. There is no sign of a face-to-face meeting between Putin and Zelensky, despite earlier White House predictions that such talks would take place. Putin has offered to host talks in Moscow, but Ukrainian officials say such a venue would be inherently insecure. Trump, who once floated the idea of acting as a third-party mediator, has since aligned himself with the Russian position that a bilateral meeting should come first.
Analysts note that Trump’s Ukraine strategy is as erratic as ever. He has demanded that Europe stop buying Russian oil, pressured allies to take action against China, and signed an order reducing tariffs on Japanese cars to 15%—a move unrelated to Ukraine but indicative of his broader, transactional approach to foreign policy. Yet, as CNN’s Alayna Treene observed, there’s little evidence that Trump has a breakthrough idea to unlock the stalled peace talks.
Meanwhile, Russia continues its efforts to destabilize the U.S.-Europe coalition. The European Commission recently reported that a plane carrying its top leader, Ursula Von der Leyen, was targeted with GPS jamming while landing in Bulgaria, with Russia suspected of involvement. Moscow dismissed the claim as “fake” and symptomatic of European “paranoia.”
As the world watches and waits, the fate of Ukraine remains in the hands of leaders who appear more interested in blaming one another than in forging a concrete path to peace. The West’s challenge is to combine pressure with dialogue, maintain unity, and ensure that any settlement preserves Ukraine’s sovereignty and delivers lasting security. Until both Moscow and Washington commit to mutual action and transparency, the prospect of ending the war in Ukraine will remain just out of reach.
For now, the diplomatic chess game continues, with Europe caught between giants and Ukraine anxiously awaiting moves that could shape its future for generations.
