Trump and Zelensky Speak by Phone as Ukraine Worries About U.S. Backing

Former President Donald J. Trump and Ukraine’s president, Volodymyr Zelensky, spoke over the phone late this week amid mounting concern in Kyiv that a second Trump administration would spell the end of American support in Ukraine’s fight against Russia.

Ukrainian officials worry that if a re-elected Mr. Trump kept to his vow to end the war quickly — he has suggested that he could end it in one day — it would allow Russia to keep the territory it occupies and leave it in a position to attack Ukraine again.

In a social media post about the call, which took place on Friday, Mr. Trump said that, as president he would “bring peace to the world and end the war that has cost so many lives.” He said both Russia and Ukraine “will be able to come together and negotiate a deal that ends the violence.”

Mr. Zelensky said in a statement on Friday that he had underlined in the call “the vital bipartisan and bicameral American support for protecting our nation’s freedom and independence.” He said he and Mr. Trump had agreed “to discuss at a personal meeting what steps can make peace fair and truly lasting.”

It was the first call between Mr. Zelensky and Mr. Trump since the former American president left office in 2020. Although the Ukrainian authorities have tried to remain neutral in the U.S. presidential campaign, officials have started building bridges with Mr. Trump’s camp, hoping to shape his views on Ukraine.

Oleksandr Kraiev, the head of the North America Program at Ukrainian Prism, a Kyiv-based think tank, said Ukrainian diplomats had been working on strategies to persuade Mr. Trump to continue supporting Ukraine, mindful that he can be unpredictable in foreign policy.
