The Republican former president has frequently criticised Zelenskiy on the campaign trail, repeatedly calling him "the greatest salesman on Earth" for having solicited and received billions of dollars of US military aid since the war broke out in 2022.
Trump has also slammed the Ukrainian leader for failing to seek peace with Moscow, and he has suggested Ukraine may have to cede some of its land to Russia to make a peace deal, a concession Kyiv considers unacceptable.
Trump's comments on the PBD Podcast on Thursday with Patrick Bet-David went a step further than his previous criticism.

He said Zelenskiy was to blame not just for failing to end the war, but for helping start it, even though the conflict broke out when Russia invaded Ukrainian sovereign territory.
"That doesn't mean I don't want to help him because I feel very badly for those people. But he should never have let that war start. The war's a loser," Trump said.
Zelenskiy presented his "victory plan" to end the war to Trump during a meeting in New York in September, an encounter both leaders described as cordial.
Trump's public comments, however, suggest he could seek to wind down aid for Ukraine if he defeats Vice President Kamala Harris, the Democratic nominee, on November 5. He has repeatedly said he could end the conflict before he takes office in January, but he has not said how.
Harris has pledged to continue supporting Ukraine, and she has portrayed a victory for the eastern European nation as a vital US national security interest. She has frequently rebuked Trump for being unwilling to stand up to Russian President Vladimir Putin.
