A conflict between politicians in Poland ⁠and Ukraine is a strategic mistake that will harm both sides, Polish prime minister Donald Tusk ⁠has cautioned, ⁠as he seeks to ​defuse a rekindled dispute over events that occurred during the second world war. Polish president Karol Nawrocki on Friday ⁠stripped Volodymyr Zelenskyy of the country’s top honour, prompting three former Ukrainian presidents and other senior officials ⁠to return their state awards to Poland. Nawrocki revoked the Order of ​the White Eagle after ‌Zelenskyy angered many in Poland ‌by renaming a Ukrainian army unit after the Ukrainian Insurgent Army, ‌nationalists who massacred Poles during the second world war.

“Wading into a conflict between politicians in Poland and Ukraine ‌is a strategic mistake that will harm both sides: business-wise, geopolitically, and reputationally. And in politics, as we know, ​a mistake is worse than a crime,” Tusk wrote in a post on X. The pro-European Tusk was elected prime minister in 2023, after leading a coalition that defeated the nationalist Law and Justice party with which Nawrocki is aligned.

Zelenskyy, in ⁠an interview posted on X, said Ukraine and Poland cannot ​be “anything but ​partners and friends,” adding that a ​political struggle could end in a “very dangerous escalation”. “Our service members ​choose a ‌heroic name for ​their unit themselves, ​and as president and supreme commander-in-chief, I must support them,” he said. “Without Ukraine, no one will be able to defend Poland. It is simply impossible.”
