A diplomatic wound that refuses to heal. Sources confirm that the Polish government has issued an ultimatum to Kyiv: drop the official designation of the Ukrainian Insurgent Army (UPA) as a ‘national liberation movement’ or face a freeze on military aid deliveries through Poland’s border. The demand landed on President Volodymyr Zelensky’s desk three days ago, according to two aides familiar with the matter.
The UPA, formed in 1942, fought both Nazi and Soviet forces. But its legacy is stained: in 1943, its units massacred tens of thousands of Poles in Volhynia and Eastern Galicia. Poland’s parliament declared the events a genocide in 2016. Ukraine’s Institute of National Remembrance, meanwhile, officially calls the UPA a ‘liberation movement’ – a classification Warsaw calls ‘a distortion of history’.
The row has been simmering for months. But it flared into an open crisis last week when Polish Prime Minister Mateusz Morawiecki told reporters: ‘Historical truth is not negotiable. We cannot accept glorification of those who killed our grandparents.’ His sentiment is widely shared. A recent CBOS poll shows 72% of Poles believe Ukraine should drop the UPA designation before any further deepening of ties.
Zelensky is caught. He needs Polish weapons and a secure supply route. Poland has provided more than €3 billion in military hardware since the 2022 invasion, and its border is the primary conduit for Western arms. But Ukraine’s nationalist far-right – small but vocal – views the UPA as heroes. On Tuesday, the Svoboda party staged a rally outside the presidential office, chanting ‘Hands off our history.’
‘He cannot afford to alienate the nationalists,’ says Oksana Syroid, a Kyiv-based political analyst. ‘But he also cannot afford to lose Poland. This is a trap of his own making.’
Uncovered documents from Ukraine’s Ministry of Culture show that in November 2023, the government quietly shelved a proposal to remove the UPA’s ‘liberation movement’ status following protests from veterans’ groups. The Polish side was informed but given no timeline for action. Now that patience has run out.
In a closed-door briefing on Wednesday, Polish Deputy Foreign Minister Paweł Jabłoński warned his Ukrainian counterpart: ‘We are not asking. We are telling. Change the law or we will reconsider your Schengen border status.’ The threat is real. Poland has already suspended truck transit permits for Ukrainian carriers this month, citing overcapacity.
Zelensky’s office has not responded to requests for comment. But a source close to the president told me: ‘He knows this is destructive. But every time he tries to move, someone in the Rada blocks it. The far right has a hammerlock on this issue.’
The stakes could not be higher. If Poland follows through, Ukraine loses its main land corridor for arms. It would be a devastating blow, especially as a fresh Russian offensive grinds into its second week. But if Zelensky bends, he risks inflaming nationalist sentiment at home, where approval ratings of 60% remain high but are slipping.
The European Union is watching nervously. Brussels has tried to mediate, but with limited success. On Friday, EU foreign policy chief Josep Borrell urged both sides to ‘de-escalate and focus on the real enemy.’ That statement earned a public rebuke from Warsaw.
This is not about history. It is about leverage. Poland sees an opening to extract a concession it has wanted for decades. And Zelensky, who once embodied Ukrainian resistance, is now trapped between the ghosts of the past and the guns of the present. The countdown to a decision has begun.
