Donald Trump has sent Volodymyr Zelensky a glowing tribute to mark the 35th anniversary of Ukrainian independence.

The US President said: โ€œI congratulate you and the citizens of Ukraine on your Independence Day … with courageous, brave, and talented people, you have built a great country.โ€

Itโ€™s a stark contrast with Mr Trumpโ€™s approach when the two leaders met in the White House in February 2025. Egged on by his vice-president, JD Vance, Mr Trump accused his guest of โ€œgambling with World War Threeโ€ and declared: โ€œYou donโ€™t have the cardsโ€.

Which Donald Trump will Andy Burnham encounter, when he travels to New York in September? The Prime Minister will be attending the UN General Assembly rather than heading to the White House, but he hopes to fit in a chat with the President – with the war in Ukraine at the top of the agenda.

Mr Burnham has followed in the footsteps of predecessor Sir Keir Starmer by pledging โ€œsteadfastโ€ support for Ukraineโ€™s efforts to defeat Russiaโ€™s invasion.

But while the UK has played its part, Ukraine needs help from the US to continue fighting.

And nobodyโ€™s quite sure how Mr Trump feels about that. In fact, itโ€™s difficult to pin the mercurial president down to anything.

He once praised Keir Starmer for doing a โ€œvery good jobโ€, only to proclaim โ€œthis is not Winston Churchill weโ€™re dealing withโ€ when the UK failed to back his war against Iran.

He portrayed himself as a peacemaker, once claiming to have โ€œended eight wars in nine monthsโ€, only to launch a conflict in the Gulf that continues to damage the global economy.

And he launched an outlandish bid to turn Canada into a US state, a prospect so fantastical that nobody is quite sure whether itโ€™s a bizarre joke.

We know, however, that Mr Trump feels Europe (including the UK) has taken advantage of US generosity for too long, allowing American taxpayers to fund their defence while showering their own citizens with lavish welfare payments.

And Mr Vance, in particular, believes European civilisation faces erasure due to liberal immigration policies, a development he regards as a threat to US interests. It means the White House feels entitled to support right-wing European politicians, who support strong borders, and attack those on the left.

At the same time, the President appears convinced that Mr Burnham is about to announce a massive expansion of North Sea oil drilling, which he heartily supports.

So the meeting could go either way. It might be handshakes and smiles, with some fine words about what a good job the new Prime Minister is doing, or it could be another showdown, with more snide comments about Winston Churchill, or worse.

Thereโ€™s no way of knowing which Mr Trump will turn up. Andy Burnham will need to be ready for triumph – or disaster.
