The site accused Bogucki of undermining Ukraine’s sovereignty and territorial integrity after he used the term “Eastern Lesser Poland” (Małopolska Wschodnia) to describe parts of western Ukraine during a parliamentary debate. Bogucki has said he supports Ukrainians fighting Russia but opposes the veneration of the Organization of Ukrainian Nationalists (OUN) and the Ukrainian Insurgent Army (UPA), wartime nationalist groups linked to the World War II‑era massacres of Polish civilians in Volhynia and Eastern Galicia. Poland officially classifies those crimes as genocide and in 2025 established July 11 as a national day of remembrance for the victims. The Myrotvorets listing comes amid a historical dispute after President Volodymyr Zelenskyy approved naming a special forces unit after the “Heroes of the UPA,” prompting sharp criticism from Warsaw. In June, Nawrocki stripped Zelenskyy of the Order of the White Eagle, Poland's highest state honor, over Ukraine's decision to name a special operations unit after the UPA. Kyrylo Budanov, head of Ukraine's Presidential Office, has warned of further escalation in Polish‑Ukrainian tensions ahead of Poland’s July 11 Remembrance Day, saying disputes over historical memory risk playing into Russia’s hands.
