The dispute, sparked in late May 2026 by President Volodymyr Zelenskyy’s decree naming a special-operations unit “Heroes of the UPA”, has deepened throughout July. Law and Justice leader Jarosław Kaczyński warned that Ukraine’s EU accession would be blocked unless it renounces the “cult of Stepan Bandera, the UPA and the OUN”, and PiS announced a Sejm resolution to that effect. Polish polls show a majority view Zelenskyy’s return of the Order of the White Eagle as an insult, while public support for military aid to Ukraine fell sharply and anti‑Ukrainian hate‑crime reports rose by more than 30% in the first half of 2026. The European Parliament condemned the naming as an “unprovoked escalation”. Ukrainian NGOs placed Polish officials on a public “enemy of Ukraine” list, prompting Polish officials to denounce the register. President Karol Nawrocki withdrew the White Eagle and pledged to criminalise the UPA flag; Prime Minister Donald Tusk announced a Warsaw “Wall of Memory” for Volhynian victims. Zelenskyy responded with a five‑point plan to open SBU archives, issue new exhumation permits and expand dialogue, which Poland welcomed but its National Security Bureau said it would not accept any narrative that relativises the massacre. In late August 2026, exhumations conducted by the Institute of National Remembrance (IPN) and partners recovered the remains of 55 Polish victims, including 26 children, from mass graves and forest sites in Ostrówki and Wola Ostrowiecka. A funeral ceremony was held on August 30, the 83rd anniversary of the 1943 attacks, involving both Catholic and Orthodox clergy. President Nawrocki used the occasion to affirm that Poland will continue seeking proper burials for those killed by the OUN-UPA, while warning that adherence to “Banderism” or nationalist collaboration remains a sign of hostility toward Poland.
