Ukrainian President Volodymyr Zelensky says he lives in fear that Donald Trump will regain the White House, branding as “very dangerous” the prospect of the former US president cutting a one-sided peace deal with Russia.

Zelensky described Trump’s repeated boast that can “stop the war in 24 hours” as a threat to Ukraine’s survival because it might impose major concessions to Russia.

“[Trump] is going to make decisions on his own, without … I’m not even talking about Russia, but without both sides, without us,” Zelensky said.

The Ukrainian feared a Trump administration would take unilateral action that fails to consider Ukraine’s perspective, noting the dearth of details around Trump’s plan.

‘A little scary’

“If he says this publicly, that’s a little scary. I’ve seen a lot, a lot of victims, but that’s really making me a bit stressed,” Zelensky said.

“Because even if his idea [for ending the war] – that no one has heard yet – doesn’t work for us, for our people, he will do anything to implement his idea anyway. And this worries me a little.”

Trump has repeatedly insisted that he is well-positioned to negotiate an end to the war that has raged for almost two years, saying he has a good relationship with both Russian and Ukrainian leaders. Throughout his political career, he has frequently lavished praise on Russian President Vladimir Putin, including after Moscow’s February 2022 invasion of Ukraine.

At a campaign rally in Georgia just days after Russian tanks moved into Ukraine, Trump described Putin as a “smart” political player and expressed admiration for Russia’s swift takeover of a vast, “great piece of land” at the cost of what he suggested were relatively minor sanctions.

The US House of Representatives impeached Trump when he was president, alleging he pressured Zelensky to pursue a politically motivated probe that might hurt Joe Biden’s chance to win the 2020 presidential election while withholding $US400 million ($606 million) in military aid that Congress approved to help Ukraine confront Russian-backed separatists in the country’s east.

The Senate acquitted Trump of the impeachment charges.

Reactor ringed with mines

Elsewhere, the head of the UN atomic watchdog on Saturday warned that mines had been re-planted around the Russian-occupied Zaporizhzhia nuclear power plant, Europe’s largest, just months after a team of international inspectors reported on their removal.

International Atomic Energy Agency chief Rafael Grossi cautioned that the presence of mines in the plant’s buffer zone, between its internal and external fences, is “inconsistent” with the agency’s safety standards, according to a readout published on the organisation’s website.

The head of Ukraine’s state nuclear company on Saturday described the alleged planting of mines as “another crime” by Russian forces that have occupied the Zaporizhzhia plant since the early weeks of the war.

In a Telegram update, Petro Kotin of Energoatom said that the situation at the plant “will remain fragile and dangerous as long as the Russians remain there.”
