“Probably it will be very, very, very difficult. And of course, in all the difficult situations, you have a chance. But we will have low chance – low chance to survive without support of the United States,” Zelensky said in an interview on the NBC News program “Meet the Press.”

An excerpt was released on Friday from the interview, which will be broadcast on Sunday.

Trump discussed the war on Wednesday in separate calls with Putin and Zelenskiy, in the U.S. president’s first big step toward diplomacy in a conflict he has promised to end quickly.

Trump later said he did not think it was practical for Kyiv to join NATO and that it was unlikely Ukraine would get back all its land. Russia, which annexed Crimea in 2014, launched a full-scale invasion of Ukraine in February 2022.

Ukraine demands Russia withdraw from captured territory and says it must receive NATO membership or equivalent security guarantees to prevent Moscow from attacking again.

Zelenskiy said in the interview that Putin wanted to come to the negotiating table not to end the war but to get a ceasefire deal to lift some global sanctions on Russia and allow Moscow’s military to regroup.

“This is really what he wants. He wants pause, prepare, train, take off some sanctions, because of ceasefire,” Zelenskiy said.
