A Donald Trump victory in the United States election on Nov. 5 would force the European Union to adapt its stance on the war in Ukraine, Hungarian Prime Minister Viktor Orbán said Sunday.

“Europe cannot bear the burden of [the war] alone, and if Americans switch to peace, then we also need to adapt, and this is what we will discuss in Budapest,” Orbán said, according to a Reuters report, referring to a Nov. 7-8 meeting of European leaders in the Hungarian capital.

Orbán also reiterated his support for Trump ahead of Tuesday’s election, which sees the former U.S. president up against current Vice President Kamala Harris.

Stressing that a Trump victory is something that “I not only believe in but I also read the numbers that way,” the Hungarian leader said that “we [in Europe] need to realize that if there will be a pro-peace president in America … then Europe cannot remain pro-war.”

Trump has promised to end the war in Ukraine “very quickly” if he wins the election, thanks to his “very good relationship” with Russian President Vladimir Putin. The former U.S. president made the pledge in a meeting with Ukrainian President Volodymyr Zelenskyy on Sept. 27.

Speaking to supporters at a rally in Michigan on Saturday, Trump complained that the U.S. is “being taken advantage of by every country all over the world, including our allies. And in many cases, our allies are worse than our so-called enemies,” he added.

On Thursday, Orbán wrote on social media that he had a phone call with Trump in which he wished the Republican candidate “the best of luck” in the election.
