Sir Keir Starmer is straining his diplomatic sinews to simultaneously praise Donald Trump’s efforts to end the war in Ukraine, while repeating calls for a completely different approach – one which ends the cosy bonhomie with Vladimir Putin, threatens the Russians with sanctions, and puts the Ukrainians back centre stage.

If that’s a message which feels like quite a stretch in writing, in person, during this morning’s call of international leaders, it must have been even more awkward.

Major shift as Trump backs peace deal over ceasefire; follow latest

Donald Trump‘s public dismissal of the Europeans’ previous calls for a ceasefire – after his tete-a-tete with Putin – has only highlighted divisions.

Of course, the prime minister and his European allies have no choice but to keep their criticism of the Alaskan summit implicit, not explicit.

Even as they attempt to ramp up their own military preparedness to help reinforce any future peace deal, they need President Trump to lead the way in trying to force President Putin to the negotiating table – and to back up any agreement with the threat of American firepower.

For Downing Street, President Trump’s new willingness to contribute to any future security guarantee is a significant step, which Starmer claims “will be crucial in deterring Putin from coming back for more”.

It’s a commitment the prime minister has been campaigning for for months, a caveat to all the grand plans drawn up by the so-called Coalition of the Willing.

While the details are still clearly very much to be confirmed, whatever comments made by Donald Trump about his openness to help police any peace in Ukraine have been loudly welcomed by all those present, a glimmer of progress from the diplomatic mess in Anchorage.

Of course, the promise of security guarantees only means anything if a peace deal is actually reached.

At the moment, as the European leaders’ bluntly put it in repeating Donald Trump’s words back to him: “There’s no deal until there’s a deal.”

Fears of Zelenskyy being painted as warmonger

There is clearly real concern in European capitals following the US president’s comments that the onus is now on Volodymyr Zelenskyy to ‘do a deal’, that the Ukrainians will come under growing pressure to make concessions to the Russians.

As former defence secretary Ben Wallace said: “Given that Donald Trump has failed to deliver a deal, his track record would show that Donald Trump then usually tries to seek to blame someone else. I’m worried that next week it could be President Zelenskyy who he will seek to blame.

“He’ll paint him as the warmonger, when in fact everybody knows it’s President Putin.”

The European leaders’ robust statements describing the “killing in Ukraine” and Russia’s “barbaric assault” are an attempt to try to counter that narrative, resetting the international response to Putin following the warmth of his welcome by President Trump – friendlier by far than that afforded to many of them, and infinitely more than the barracking President Zelenskyy received.

They’ll all be hoping to avoid a repeat of that on Monday.
