Zelensky asked the United States to maintain its support for Ukraine in spite of "the tough dialogue" between the two sides after traveling to the United Kingdom to participate in a summit of European leaders.

 During Friday's altercation in the Oval Office, Zelensky, Trump, and US Vice-President JD Vance interrupted one another.  Vance accused Zelensky of being ungrateful after Trump threatened to cut ties with Russia unless he made a deal.

 Despite the support of European leaders, Zelensky had to "find a way" to mend his connection with Trump, according to the secretary general of NATO.

Zelensky posted 14 messages on X when he arrived in the UK, restating calls for US security guarantees to be included in any "just and lasting" peace agreement to end the conflict with Russia.

 Although he acknowledged that Trump wished to put an end to the conflict, which started on February 24, 2022, when Russia launched a full-scale invasion of Ukraine, he added that no one desired peace more than Ukraine.

 A contract to grant the United States access to Ukraine's rare earth mineral reserves was supposed to be signed after the disastrous White House meeting.  Instead, before it could be signed, Zelensky was instructed to depart early.

Trump subsequently told reporters that the Ukrainian president "overplayed his hand" in the conversation and that in order to resume discussions with the United States, he would need "to say 'I want to make peace'".

 Zelensky stated on Saturday that Ukraine was prepared to sign the minerals deal as "the first step toward security guarantees" from the United States. He has been stating this for days, but Trump has not agreed.

 "But it's not enough, and we need more than just that," he stated.  "A ceasefire without security guarantees is dangerous for Ukraine."

 "Every Ukrainian wants to hear a strong US position on our side," he continued.  It makes sense that the US would want to talk to [Russian President Vladimir] Putin.

However, the United States has consistently advocated for "peace through strength."  And if we band together, we can take decisive action against Putin.

 Zelensky's trip to Washington was described as a "complete diplomatic failure of Kyiv" by a spokesman for the Kremlin's foreign ministry in Russia.

 Maria Zakharova reiterated Russia's demand to take all of the territory it presently occupies and claimed that the Ukrainian president is "obsessed" with extending the conflict.

Zelensky visited UK Prime Minister Sir Keir Starmer, who "retains unwavering support for Ukraine," ahead of the London summit, where European leaders will continue to debate efforts to negotiate a peace settlement.

 Sir Keir declared that the UK would support Ukraine "for as long as it may take" and informed Zelensky that he was "very, very welcome here in Downing Street" while speaking in his office.

 He continued: "A lasting peace for Ukraine based on sovereignty and security for Ukraine - so important for Ukraine, so important for Europe and so important for the United Kingdom."

 Senior European politicians have also backed Ukraine in the wake of Friday's historic events in the United States.

Social media posts supporting Ukraine were made by the leaders of Germany, France, Spain, Poland, and the Netherlands, and Zelensky personally responded to each one to express gratitude for their support.

 "Russia is an aggressor," wrote French President Emmanuel Macron on social media.  Ukraine is the victim.  Three years ago, we were correct to support Ukraine and impose sanctions on Russia, and we will continue to do so."

 "No one wants peace more than the citizens of Ukraine," stated Germany's outgoing chancellor Olaf Scholz. Friedrich Merz, who is expected to succeed him, added that "we stand with Ukraine" and "we must never confuse aggressor and victim in this terrible war."

Mark Rutte, the head of NATO, told the BBC on Saturday that he had visited with Zelensky twice since the White House meeting and that "we have to respect" what Trump has done for Ukraine thus far.

 He mentioned how Ukraine was able to "fight back" after the first Trump administration approved the export of Javelin anti-tank missile weapons.

 The conflict was started by Putin two years after Trump's resignation.

For months, Russia has been gradually gaining ground on the battlefield.

 Shortly after Zelensky left the White House, authorities reported that a "massive" overnight drone strike in the northeastern Ukrainian city of Kharkiv injured 12 people, including two children.

 Four female patients from a city center hospital were among the casualties.  According to the Ukrainian prosecution service, shops, pharmacies, cafes, and residential structures were also damaged.

 The discussion deteriorated on Friday when US Vice-President JD Vance, who was there in the room with other lawmakers, informed Zelensky that diplomacy was the only way to end the war.

In response, Zelensky questioned "what kind of diplomacy?" referring to a ceasefire agreement reached in 2019 three years prior to Russia's full-scale invasion, during which time Moscow was equipping and assisting separatist rebels in the eastern region of Ukraine.

 Zelensky was then accused by the vice president of disrespecting the issue and "litigating" it in front of the media.
