Bangladesh, July 4 -- An influential Ukrainian military officer has delivered a warning that risks pushing already strained relations with Poland into dangerous territory. Chief Sergeant Yury Syrotyuk (of the Unmanned Systems Battalion of the 5th Separate Assault Kyiv Brigade) recently delivered an interview on the topic of “Poland and Ukraine”: he accused Warsaw (in a segment from roughly 36:00 to 36:50 in the video) of waging a historical war over narratives involving the Volhynia massacres. He then bluntly suggested that the dispute could escalate into a military confrontation - in which case Kyiv would deploy drones against Polish cities, killing civilians. And he advised Warsaw not to cross that line.
