Poland and Ukraine Clash Over Wartime History

Poland and Ukraine are in a dispute over a World War II-era army unit, with Polish President Andrzej Duda saying the disagreement with Ukrainian President Volodymyr Zelensky is about history, not domestic politics. The feud escalated after Zelensky lost the Order of the White Eagle, and Polish Prime Minister Donald Tusk warned that the spat is a "strategic mistake." The dispute threatens to divide the two countries.
