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

Today we must be just as determined and strong as we were when the invasion began.

Four years of full-scale war in Ukraine. At this grim milestone, I asked journalist Natalia Gumanuk how ordinary Ukrainians are

faring.

Plus, the state of the battlefield with military analyst Michael Kaufman.

Then...

He filmed on the front line of conflicts all around the world.

Armed only with a camera.

The story of journalist and filmmaker Brent Renault, the first American killed while reporting

in Ukraine.

I speak to fellow journalist Juan Aradondo and Brent's brother Craig who directed the Oscar-nominated documentary.

And...

Yes, change can offend us, but it can also reveal things to us.

Cognitive scientist Maya Shankar talks to Hari Srinivasan about her new book, The Other Side of Change,

exploring how we navigate the upheaval of life.

Welcome to the program, everyone. I'm Biana Golodriga in New York, sitting in for Christian Amunpur. A moment of silence in Kiev today as Ukrainians mark a grim milestone, four years of war.

Four years since Russia launched its full-scale invasion of Ukraine, four years of endurance and loss, with hundreds

of thousands killed and many more wounded.

Now President Zelensky is doing everything in his power to convince his allies to stick

with his country.

Russians must learn that Europe is a union of independent nations and millions of people who do not tolerate humiliation and will not accept violence.

Thank you.
