Polish-Ukrainian solidarity over Russian threat undermined by bitter historical dispute

A bitter historical dispute over Ukrainian nationalist fighters responsible for the deaths of approximately 100,000 Poles during World War II is now undermining the strong solidarity between Poland and Ukraine. This resurgence of tension comes years after Poland became a crucial ally and refuge for millions of Ukrainians fleeing Russia's full-scale invasion in February 2022. Poles, remembering their own history with Russia, had mobilized extensively to provide food, shelter, and support to Ukrainian refugees. However, Kyiv's decision to honor certain WWII fighters, viewed by Poland as perpetrators of massacres, has reignited simmering animosity. The conflict has led to sharp rhetoric and mutual accusations, with Poland now threatening to obstruct Ukraine's path to European Union membership until the historical grievances are addressed. This historical friction casts a shadow over the once-unwavering support, highlighting the complex and often fraught relationship between the two nations.
