On the 2nd, Zelensky attended the European leaders' summit in London. After the summit, he stated on the same night that an agreement to end the war between Ukraine and Russia was "still very, very far away."
At the same time, despite the deteriorating relationship with Trump, he expressed hope that the U.S. would continue to support Ukraine. He said, "I believe Ukraine has built a sufficiently strong partnership with the United States."
In response, Trump, on the 3rd, criticized Zelensky on his social media platform, Truth Social, accusing him of not desiring peace. He reiterated his view that Zelensky was hindering peace negotiations and continued, "This is the worst statement Zelensky could make. The U.S. will not tolerate this any longer! As I’ve said before, as long as America supports him, this man does not want peace."
Trump also commented on the European leaders' summit, writing, "In terms of showing strength against Russia, this was probably not a great statement. What are they all thinking?"
During the summit, European leaders discussed efforts toward peace in Ukraine. They agreed on a four-point plan that would guarantee Ukraine’s defense if a peace agreement with Russia is reached.

At a press conference on the 3rd, Trump reiterated his belief that Zelensky should be "more grateful" for the support Ukraine has received from the U.S. over the past three years.
During a summit at the White House on February 28, both Trump and Vice President J.D. Vance expressed anger towards Zelensky for lacking gratitude. There was even a moment when Vance, speaking to the press, demanded that Zelensky simply say "thank you."

Due to these intense exchanges, the deal allowing the U.S. to utilize Ukraine's rare earth minerals (rare earth elements) ended without success.
At a press conference on the 3rd, Trump stated that he does not believe the deal has disappeared, and added that he would provide an update on the 4th.
After the European leaders' summit in London, the UK and France proposed a "coalition of the willing" to protect Ukraine and prevent Russia from invading again after a peace agreement.
UK Prime Minister Keir Starmer mentioned that there is some support for the proposal to send ground troops and aircraft to Ukraine, though he added that each country should discuss it domestically.
Nordic countries suggested they would be positive about the proposal if supported by the U.S.
Under Trump, the U.S. has shifted its stance on the war in Ukraine. Trump has publicly stated that he wants to end the war and had a lengthy phone discussion with Russian President Vladimir Putin in February. U.S. and Russian officials are moving forward with peace talks excluding Ukraine.
Trump stated that he trusts Putin and criticized Zelensky, calling him a dictator. He also claimed that the war was started by Ukraine, not Russia, which has puzzled Western allies.
In this context, U.S. CBS reported on the 3rd that White House officials said, "We are temporarily halting and reviewing our support to ensure that American assistance definitely contributes to the resolution."
According to U.S. Bloomberg, which first reported the suspension of aid, all military supplies, including American military equipment not currently in Ukraine, weapons passing through Poland, and those at Polish bases, will have their provision temporarily suspended.
