Oksana Markarova, the Ukrainian Ambassador to the United States, said on Sunday that the country is not ready to give up its territories and that if they are unsuccessful in the war, they will prevail.

There are no independent republics on the territory of Ukraine. Russia attacked us. She told NBC's "Meet the Press" that Russia illegally occupied part of Luhansk.

Russia waged a war on the independent country. If there is a respectful sovereignty and territorial integrity, which is a firm basis for any U.N. charter or any international organization, can anyone?

I think we should not ask Ukraine what they are willing to give up in order for Russia to stop this aggression. All of us should be asking each other what we are prepared to do to stop it.

Thousands of people have been killed in a war that has been started by Russia President Vladimir Putin. Russian forces have been accused of carrying out war crimes by Ukrainian officials.

The besieged Mariupol will go down in history for war crimes. Zelenskyy said in a video address that the terror the occupiers did to the city will be remembered for a long time.

Millions of people have left their homes because of the war. Last week, the US announced a plan to accept 100,000 refugees. Chuck Todd asked Markarova if that was enough during the interview.

More than 3.6 million refugees are in Europe. Most of the people want to go back, but the focus is on sanctions and weapons to stop Putin. We are grateful for everyone and I am happy that the US is joining the group of countries that are helping us with weapons and sanctions.

Whether it will be enough depends on how quickly we stop the war. Let's focus on that. There will not be more refugees if the war is stopped.
