Russia’s Foreign Ministry on Sunday accused Kyiv of “systematic infliction of damage” to the Zaporizhzhia plant and warned of the possible fallout from a catastrophe there. In the ABC interview, Zelenskyy said Ukraine is prepared for a possible disaster there.

Zelenskyy said he was not particularly concerned that Wagner Group leader Yevgeny Prigozhin may be back in Russia after leading an aborted rebellion against the authority of Russian President Vladimir Putin.

“As of today, he has become a political figure,” he said of Prigozhin. “And this, to me, must have been his primary objective.”

He also said that he was not worried about Prigozhin possibly resuming command of the Wagner Group or bringing some fighters back into the war, given that those soldiers have been unable to defeat Ukraine’s forces so far.

Speaking before the start of a NATO summit that will concern itself at least partially about the war, Zelenskyy said Ukraine remains adamant that will not yield any territory to Russia to end the war, including Crimea, which was seized in 2014.

“No territory,” he told host Martha Raddatz.

Ukraine’s president also said he didn’t see former President Donald Trump’s assertion that he could end the war in a single day as realistic, given that Trump didn’t attempt to fix things between Russia and Ukraine during his presidency.

“It seems to me that the sole desire to bring the war to an end is beautiful,” Zelenskyy told Raddatz. “But this desire should be based on real-life experience. Well, it looks as if Donald Trump had these 24 hours once in his time. We were at war. Not a full-scale war, but we were at war. And as I assume, he had that time at his disposal. But he must have had some other priorities.”

Zelenskyy also said he hopes Ukraine’s ongoing counteroffensive can gain speed.

“All of us we want to do it faster because every day means new losses of Ukrainians,” he said.
