Ukrainian President Volodymyr Zelensky returned Poland's highest state honor this weekend after Polish President Karol Nawrocki revoked it over Zelensky's decision to name a military unit after a WWII paramilitary group accused of massacring tens of thousands of Poles — another diplomatic clash between allies that American taxpayers are footing the bill for.

The dispute exposes the fragility of the coalition Washington has sustained with billions in aid. While Americans struggle with grocery prices and inflation, the leaders they're subsidizing are trading medals and insults over 80-year-old history.

Nawrocki revoked the Order of the White Eagle — awarded to Zelensky in 2023 by then-President Andrzej Duda for "services to security, resilience and the defence of human rights" — after Zelensky issued a May 26 decree naming a unit of Ukraine's Special Operations Forces after the Ukrainian Insurgent Army, or UPA.

"For the majority of Polish society, the Ukrainian Insurgent Army remains above all a formation responsible for cruel crimes against the citizens of the Polish Republic during World War II," Nawrocki said in a 13-minute social media address. According to Breitbart, Poland's parliament recognized the UPA's wartime crimes as genocide in 2016.

The UPA fought for Ukrainian independence against both Nazi and Soviet forces, but is accused in Poland of killing tens of thousands of Poles, most in the Nazi-occupied regions of Volhynia and Eastern Galicia. Ukrainians counter that armed formations on both sides — including Polish underground forces — carried out attacks and reprisals that produced large-scale civilian casualties among both Poles and Ukrainians, Breitbart reported.

Zelensky mailed the order back to Nawrocki's office, posting photos of the medal and a postal receipt on social media. He wrote that the award "was meant for the Ukrainian People and our army" and that "the future will confirm the respect Ukrainians deserve." Ukrainian intelligence chief Kyrylo Budanov called Nawrocki's decision "an unfriendly act toward our people" and "a gift to the Moscow aggressor, which will certainly use it against both of our countries." Four Ukrainian officials said they would return their Polish honors.

Not everyone in Kyiv backed the gesture. Former Prime Minister Arseniy Yatsenyuk wrote that "one harmful and incorrect decision by the current president of Poland cannot be corrected by other incorrect decisions of ours."

CBS and the Boston Globe both characterized Nawrocki as "a nationalist politician who has exploited anti-Ukrainian sentiment for electoral gain" — editorial framing Breitbart did not adopt. Breitbart instead supplied the 2016 genocide recognition and the Ukrainian counter-argument about Polish forces' role, context both legacy outlets omitted.

Polish Prime Minister Donald Tusk, Nawrocki's political rival, urged both leaders to "tone down emotions, not stoke tensions," warning the row "delights Putin and shocks our allies." Ukraine's Foreign Minister Andrii Sybiha likewise urged both sides to leave "sensitive chapters of their shared history to professional historians," according to Breitbart.

Nawrocki insisted revoking the honor does not mean Poland's support for Ukraine will decrease. The timing is nonetheless awkward: Poland is scheduled to host a major event on Ukraine's postwar reconstruction next week, with Zelensky expected to attend.

If two of the most prominent allies in the war against Russia can't stop feuding over 1940s history while bombs are still falling in 2026, the question for Americans is straightforward: what exactly are the billions buying — and who's accountable for the check?
