Donald Trump says there has been agreement to begin negotiations about ending the war in Ukraine, after holding phone calls with Vladimir Putin and Volodymyr Zelenskyy.

It is the US president’s first big step towards diplomacy over a conflict which he promised to end within 24 hours of being inaugurated.

“We both agreed, we want to stop the millions of deaths taking place in the War with Russia/Ukraine,” Mr Trump posted on Truth Social following discussions with Russia’s president.

He said the pair would “work together, very closely” towards winding down the conflict and “agreed to have our respective teams start negotiations immediately”.

A Kremlin spokesperson said Mr Putin and Mr Trump had agreed to meet, with the Russian president inviting the US leader to visit Moscow.

“President Putin, for his part, mentioned the need to eliminate the root causes of the conflict and agreed with Trump that a long-term settlement can be achieved through peaceful negotiations,” said Kremlin spokesperson Dmitry Peskov.

Meanwhile, Ukraine’s president wrote on X that he had a “meaningful conversation” by phone with Mr Trump to discuss “opportunities to achieve peace” and the preparation of a document governing security and economic cooperation.

“No one wants peace more than Ukraine. Together with the US, we are charting our next steps to stop Russian aggression and ensure a lasting, reliable peace,” he said.

Mr Trump added that his phone conversation with Mr Zelenskyy “went very well”, suggesting that “he [Mr Zelenskyy], like President Putin, wants to make PEACE”.

On social media, the US president said: “It is time to stop this ridiculous War, where there has been massive, and totally unnecessary, DEATH and DESTRUCTION. God bless the people of Russia and Ukraine!”

Trump’s bombshell phone call

Trump’s bombshell phone call leaves questions unanswered.

He says there have been NATO efforts all day to stop the damage to unity done by defence secretary Pete Hegseth, who said it’s unrealistic that Ukraine will get all of its land back in a peace deal or join NATO.

That impression of unity is crumbling.

Trump’s call with Putin is a break from three years of firm determination by NATO members to be united behind the principle of not talking about Ukraine without Ukraine.

The president’s announcement that Russian and US teams will start negotiations does not make clear whether they are bilateral talks or involve Kyiv.

Donald Trump seems to have made commitments in that phone call with Putin that the Russians expect him to hold himself to – what are those commitments?

On Wednesday, the US defence secretary delivered a blunt statement on the new US administration’s approach to the nearly three-year-old war.

Speaking at a NATO meeting in Brussels, Pete Hegseth said a return to Ukraine’s pre-2014 borders was unrealistic and the US did not see NATO membership for Kyiv as part of a solution to the war.

“Chasing this illusionary goal will only prolong the war and cause more suffering,” he said.

Separately the US and Russia agreed to a prisoner swap. America freed a Russian cybercrime boss in return for Moscow’s release of schoolteacher Marc Fogel, a US official said on Wednesday.

Meanwhile at a White House news conference on Wednesday, press secretary Karoline Leavitt said she was “not aware of” Mr Trump putting any preconditions on his meeting with Mr Putin.

Mr Trump said the peace negotiations will be led by secretary of state Marco Rubio, director of the CIA John Ratcliffe, national security advisor Michael Waltz, and ambassador Steve Witkoff.

US troops will not be used to secure the peace in Ukraine following any ceasefire deal with Vladimir Putin, Donald Trump’s new defence secretary has declared, as he signalled a dramatic shift in American foreign and defence policy away from Europe.

Pete Hegseth also said it is “unrealistic” to think Ukraine can return to its pre-2014 borders and he ruled out NATO membership as way to guarantee Kyiv’s security.

This will be a huge blow for Volodymyr Zelenskyy.

The interventions came at the opening of a meeting of allies in Brussels on Wednesday.

Mr Hegseth said Washington must focus on the threat posed by China and securing its own borders.

He added: “Stark strategic realities prevent the United States of America from being primarily focused on the security of Europe.

“As the United States shifts its attention to these threats, European allies must lead from the front,” Mr Hegseth said in opening remarks at the gathering of NATO and non-NATO countries that are providing military support to Ukraine.

NATO spending

Mr Trump – a long-time critic of the alliance, which he sees as containing freeloaders that benefit from American military strength without investing in their own security – has said all NATO allies should increase defence spending to 5% of GDP.

This is more than double the current target. The UK is only spending 2.3%.

While still supportive of NATO, Mr Hegseth warned that America’s patience was limited.

“Our transatlantic alliance has endured for decades. And we fully expect it will sustained for generations more. But this won’t just happen,” he said.

He continued: “It will require our European allies to step into the arena and take ownership of conventional security on this continent.

“The United States remains committed to the NATO alliance and to the defence partnership with Europe.

“Our relationship will prioritise empowering Europe to own responsibility for its security.”

Ukraine-Russia war

Mr Hegseth also had strong words about Russia’s war in Ukraine, which he said “must end”.

Speaking frankly, he dismissed a fundamental Ukrainian goal to recapture all its territory – including Crimea and swathes of the Donbas that were seized by Russia in 2014 when Mr Putin first invaded his neighbour. This aim had previously been backed by the UK and other allies.

“We want… a sovereign and prosperous Ukraine. But we must start by recognising that returning to Ukraine’s pre-2014 borders is an unrealistic objective,” he said.

“Chasing this illusory goal will only prolong the war and cause more suffering.”

The US defence secretary said that a durable peace must include robust security guarantees to ensure that the war won’t begin again – but he made clear that the US would not be part of that effort on the ground and it could not be a NATO operation.

It was not immediately clear, however, whether the US military may help to provide protection from a distance.

“These security guarantees should not be provided through NATO membership, but must instead be backed by capable European and non-European troops,” the US defence secretary said.

“If these troops are deployed as peacekeepers to Ukraine at any point, they should be deployed as part of a non-NATO mission and not covered under Article 5. There also must be robust international oversight of the line of contact.”

Article 5 of NATO says an armed attack on one member is considered an attack on all.

Mr Hegseth continued: “To be clear, as part of any security guarantee, there will not be US troops deployed to Ukraine.”

His words will be a significant setback for Kyiv.

President Zelenskyy told Sky News last week that any peacekeeping force that did not include a US element would be a “major mistake”, signalling that he did not believe European militaries alone could deter Moscow.

The retreat of the US from its leadership role in Ukraine was clear in the choreography of the Ukraine Defence Contact Group meeting – an alignment of allies gathered together by Washington under Joe Biden and his defence secretary Loyd Austin after Russia launched its full-scale invasion almost exactly three years ago.

Future of European security

The regular meetings have until now always been chaired by the US.

Wednesday’s meeting, however, was led by John Healey, the UK defence secretary.

Mr Hegseth made clear that European allies would need to step up and take on much more of the effort to provide Ukraine with weapons and non-military support.

“Safeguarding European security is an imperative for European members of NATO. As part of this, Europe must provide the overwhelming share of future lethal and nonlethal aid to Ukraine,” he said.

This means donating more ammunition, expanding Europe’s defence industrial base and rallying the public to be willing to respond to the threat the continent faces.

“Part of this is speaking frankly with your people about how this threat can only be met by spending more on defence and investing strategically,” Mr Hegseth said.

“Increasing your commitment to your own security is a down payment for the future.”

Earlier, NATO Secretary General Mark Rutte said he agreed with US president Donald Trump on the need for Washington and European allies to share the burden of military aid for Ukraine more equally.

Elon Musk joined Donald Trump in the Oval Office as the US president signed an executive order allowing the tech billionaire to make large-scale reductions in the federal workforce.

As head of the Department of Government Efficiency (DOGE), an advisory group, Mr Musk says he wants to add “common sense controls” to government and ensure taxpayer money is spent wisely.

The executive order requires government agencies to work with DOGE, in some cases so they can be “eliminated or combined because their functions aren’t required by law”.

In addition, the agencies have been told to “hire no more than one employee for every four employees that depart from federal service”, with exceptions for immigration, law enforcement and public safety.

Answering reporters’ questions in the Oval Office, Mr Musk was asked to respond to accusations he is orchestrating a “hostile takeover” of government in a non-transparent way.

The Tesla CEO and owner of X said “the public voted for major government reform… and they’re going to get what they voted for. And that’s what democracy is all about”.

“We have this unelected, fourth unconstitutional branch of government, which is the bureaucracy, which has in a lot of ways, currently more power than any elected representative,” he added, while stood alongside his son X Æ A-12.

Mr Musk also spoke about what he described as a lack of Treasury controls. “Your tax dollars need to be spent wisely on things that matter to the people… it’s just common sense. It’s not draconian or radical”.

When challenged about what checks and balances are in place to ensure accountability for Mr Musk, who is unelected, he replied: “We are trying to be as transparent as possible… I don’t know of a case where an organisation has been more transparent”.

Another reporter raised the possibility of conflicts of interest, pointing out Mr Musk has received billions of dollars in federal contracts.

“All of our actions are fully public,” he says, adding that he fully expects to be “scrutinised nonstop” – comparing it to “a daily proctologist exam” – but also admitting “we will make mistakes, but we’ll also fix the mistakes very quickly”.

“Some of the things that I say will be incorrect and should be corrected,” he said. “So nobody can bat 1,000.”

Earlier on Tuesday, Mr Musk posted an attack aimed at judges who have issued rulings that paused Mr Trump’s executive actions.

“Democracy in America is being destroyed by judicial coup,” Mr Musk wrote on X.

The president voiced a similar complaint in the Oval Office alongside Mr Musk.

“We want to weed out the corruption. And it seems hard to believe that a judge could say, we don’t want you to do that,” he said.

“So maybe we have to look at the judges, because that’s very serious. I think it’s a very serious violation.”

Mr Trump also held discussions with Jordan’s King Abdullah at the White House.

The president repeated his pledge to “take Gaza” and move its residents to Jordan and Egypt, something the king has rejected.
