KYIV, Ukraine (AP) — Ukrainian President Volodymyr Zelenskyy says U.S. President-elect Donald Trump is “strong and unpredictable” and those qualities can be a decisive factor in his policy approach to Russia’s invasion of Ukraine. But Zelenskyy says it won’t be possible to end the almost three years of war in one day as Trump claimed during his election campaign that he could do. Zelenskyy said in a Ukrainian television interview late Thursday that fighting on the battlefield “can end quite quickly if Trump is strong in his position.” Trump takes office on Jan. 20. He hasn’t publicly fleshed out his policy on Ukraine but his previous comments have put a question mark over whether the United States will continue to be Ukraine’s biggest and most important military backer.
