Mark Rutte, the Secretary General of NATO, shared a positive outlook following the conversation. "Great call with [Trump], Zelensky, and European leaders ahead of President Trump's meeting with Putin in Alaska. We are united in pushing to end this terrible war… and achieve just and lasting peace,"Rutte said via social media. "Appreciate Trump's leadership and close coordination with allies. The ball is now in Putin's court." Shortly after the call,Vance spoke to U.S. soldiers at a military base in England, where he is currently on a trip with his family.

Trump referred to the European leaders as "great people who want to see a deal done," in a Truth Socialpostearly Wednesday. After the conversation, Zelensky said that Trump struck down the idea that Russia could veto Ukraine's NATO membership aspirations and reiterated calls for possible economic penalties on Russia—which the U.S. President previously promised to enact—should a cease-fire deal not be reached.

Zelensky, backed by his European allies, staunchly denounced that idea, stating that Ukraine will not "gift their land to the occupier." The Ukrainian leader doubled down on his position on Wednesday, saying: "I stress that any questions concerning our country's territorial integrity cannot be discussed without regard for our people, for the will of our people and the Ukrainian constitution." World leaders, such as French President Emmanuel Macron and U.K. Prime Minister Sir Keir Starmer, had previously urged Trump toconsider invitingUkraine to the Putin summit while reiterating their support for the eastern European nation. "The path to peace in Ukraine cannot be decided without Ukraine," the leaders of France, Italy, the U.K., Germany, Poland, and Finlandsaid in a statementon Saturday. "We remain committed to the principle that international borders must not be changed by force." Russian troops advanced deeper into Ukraine on Tuesday, in what some haveviewed as a bidto pressure Kyiv into considering Putin's demands for more territory. "We see that the Russian army is not preparing to end the war. On the contrary, they are making movements that indicate preparations for new offensive operations," Zelenskysaid. Furthermore, ahead of his call with Zelensky and others on Wednesday, Trump strongly criticized what he claimed has been "very unfair" media coverage of his upcoming talk with Putin. "Very unfair media is at work on my meeting with Putin. Constantly quoting fired losers and really dumb people," Trumpsaid via Truth Social, before referencing recent comments made by his former national security adviser John Bolton, who asserted that "Putin has already won," in an interview withThe Atlantic. "What's that all about? We are winning on EVERYTHING. The fake news is working overtime. (No tax on overtime)," Trump maintained.
