Hello everyone and welcome to Amunpur. Here's what's coming up.

Trump and Putin meet in Alaska, but can any amount of talking put an end to Russia's invasion of Ukraine?

We bring you a special program, a look at the big picture, the history and what's at stake.

Make a peace in Ukraine. This is our plan.

That's what we really want and that what we will try to do.

President Volodymyr Zelensky in his own words, on what it will take to stop the bloodshed.

Then...

It's a serious operation with serious purpose.

The Kremlin's view, a rare conversation with Putin's right-hand man, on his reasons for invading Ukraine in the first place.

Plus, American investor Bill Browder talks to Walter Isaacson about Russia's endgame. Welcome to the program, everyone. I'm Christiana Manpur in London.

Donald Trump said he'd end the Ukraine war before even taking office,

but the war is still raging and the president is still struggling with how to stop it.

Meeting Vladimir Putin face-to-face in Alaska is one of his ways. It's the first such summit

since Putin's full-scale invasion. Notably absent, though, is Ukraine's president, Volodemir Zelensky.

But in virtual talks ahead of the Alaska meeting, he said Trump agreed on the need for a ceasefire

first. Trump also threatened severe consequences if Putin isn't serious. Since Zelensky will not

be at the meeting, as we said, we want to devote

this program to Ukraine's position, remarkably consistent from the beginning, as you'll hear,

when we spoke at the Munich Security Conference in February, just after Zelensky had spoken

to Trump on the phone. You, after your phone call with President Trump, said that you did not hear enough detail

to make this a peace plan.

Can you just elaborate what you meant by that?
