The latest talking took place in Berlin on Sunday, when the US envoy Steve Witkoff and Donald Trump's son-in-law Jared Kushner met with Ukraine's President Zelensky, as so often in the past.

The US delegation insisted that progress had been made.

Europe editor Katja Adler is in Berlin and says the US certainly wants that to be the case.

Donald Trump is getting really impatient.

His administration recently published its national security strategy, where it prioritises stabilising US relations with Moscow.

So ideally, Donald Trump really wants an end to all of this.

But

Ukraine is refusing to roll over.

Vladimir Zelensky here in Berlin today said, yeah, he's willing to compromise on some things.

He's no longer insisting on NATO membership as part of a peace deal, but he is insisting on getting cast iron security guarantees from his allies, including the US, to make sure that Russia doesn't invade again.

Now, talks here...

with US negotiators were so intense that we're told they're going to roll over into tomorrow morning.

And I tell you who else is coming here tomorrow, and that is a big list of big European names.

Emmanuel Macron of France, Sakhir Starmer, the Danish, the Swedish, the Dutch prime ministers, I'm told, the Polish prime minister, NATO secretary general, all of them to hold Volodymyr Zelensky's hand?

No, it's because they are convinced this isn't just about Ukrainian sovereignty going forward.

It's about the future security of Europe.

The host of this meeting, the German Chancellor, Friedrich Merz, says this is a Russian war of aggression against Ukraine and against the rest of Europe.

These European leaders are worried that if there is a peace deal that's too soft on Russia, then Vladimir Putin will come back for more.

And while this diplomatic ping pong continues, of course, so does the war on the ground in Ukraine, claiming more and more lives.
