President Trump cast doubt on whether Ukrainian President Volodymyr Zelensky is ready to back the latest peace proposal — as his son warned that the commander-in-chief may grow impatient and walk away from Ukraine.

“I have to say that I’m a little bit disappointed that President Zelensky hasn’t yet read the proposal, that was as of a few hours ago,” Trump told reporters before becoming the first president ever to host the ritzy Kennedy Center Honors.

“His people love it, but he hasn’t. Russia’s fine with it.”

Last month, US and Ukrainian negotiators hashed out a 19-point peace plan that included several provisions that Russian tyrant Vladimir Putin promptly rejected.

It’s unclear how much of that was reworked in the time since Russia rejected it.

“I think he may,” Donald Trump Jr. said at the Doha Forum on Sunday when asked whether his father will walk away from Ukraine.

“What’s good about my father, and what’s unique about my father, is you don’t know what he’s going to do,” he continued. “The fact that he’s not predictable … forces everyone to actually deal in an intellectually honest capacity.”

Zelensky, however, has commended the negotiations to end the bloody war ravaging his country and stressed that his team is still working out the finer details of the plan.

“I am grateful for a very focused, constructive discussion,” Zelensky wrote on X Saturday.

“We covered many aspects and went through key points that could ensure an end to the bloodshed and eliminate the threat of a new Russian full-scale invasion, as well as the risk of Russia failing to honor its promises, as has happened repeatedly in the past.”

Trump’s son-in-law Jared Kushner and special envoy Steve Witkoff met with Ukrainian negotiator Andriy Hnatov and Rustem Umerov, secretary of the National Security and Defense Council of Ukraine, last Friday in Florida. 

Zelensky trekked to London on Monday to huddle with European leaders amid the talks to end the war.

Throughout his peace negotiation efforts, Trump has wavered between faulting Ukraine or Russia more for prolonging the brutal conflict that is set to mark its fourth anniversary in February. 

In September, Trump ripped into Putin and suggested that Russia might be a “paper tiger,” adding that he felt Ukraine might be able to regain its lost territory. Weeks later, the president had seemingly soured on Ukraine again and publicly declared his belief that “Putin wants to end the war.”

Last month, staunchly pro-Ukraine lawmakers in Congress were apoplectic over a draft 28-point peace plan that would’ve seen Kyiv make massive concessions such as ceding the entire Donbas region, which the Russians have been unable to fully take over for more than a decade, including the period before its invasion, when it helped fuel a civil war in Ukraine.

Ukraine would also have to commit to never joining NATO, shrink its military force from roughly 900,000 to 600,000 personnel, and provide amnesty to everyone involved in the war, meaning that Russians couldn’t face war crime claims. Russia was asked to make a few concessions in that proposal. But Trump’s team quickly overhauled the plan during a series of talks with Ukrainian negotiators.

Trump Jr. took swipes at Zelensky and ripped into how the Ukrainian leader is often portrayed on the world stage and in American media. 

“Because of the war, and because he’s one of the great marketers of all times, Zelensky became a borderline deity, especially to the left, where he could do no wrong; he was beyond reproach,” Trump Jr. chided.

“We want peace. We want to stop the death,” the Trump scion later added.

Public support for Ukraine in its war of defense against Russian invaders has jumped to 62%, according to a recent Reagan National Defense survey of US adults, which marks an increase from the prior poll. 

A solid 64% backed sending weapons to Ukraine, and 70% were doubtful that Russia could be trusted to uphold its end of the bargain in any deal.
