The Ukrainian president said there is no direct agreement between Russia and Ukraine on this issue.

Never thought of it.

We were just doing it for fun, just for the love of terriers, but thinking, yeah, why not?

The report is by the Center for International and Strategic Studies in Washington.

It puts Russian casualties at 1.2 million and Ukrainian ones at up to 600,000.

Of those casualties, the dead are estimated at up to 325,000 Russians and up to 140,000 Ukrainians.

The Russian army is three times larger than the Ukrainian one, so Ukraine is losing a bigger share of its smaller army.

But the study's authors did note Russia has suffered more losses than any major power in any war since World War II.

They were just using a lot of force to arrest me.

And I was screaming.

I was crying.

I was so scared.

I've never been arrested in my life.

Zelensky began with a reference to the movie Groundhog Day and said Ukrainians have been reliving the same day during four years of Russia's full-scale war.

Europe, he says, is also in a loop and it's going to kill them.

He wants the continent to wake up and see the world order is changing quickly and that they risk being left behind.

Zelensky issued this wake-up call after a week in which global leaders at Davos, including French President Emmanuel Macron and Canadian Prime Minister Mark Carney, raised their concerns about the historic transatlantic relationship with the U.S.

Zelensky implored Europe to unite and stop relying on the U.S., especially with an aggressive Russia at Europe's doorstep.
