Zelenskyy returned Poland's Order of the White Eagle after Polish President Nawrocki revoked it, escalating a dispute over Ukraine's decision to name a military unit after a paramilitary organization accused of World War II atrocities against Poles. The move threatens one of Ukraine's most consistent European supporters at a critical moment in the conflict with Russia, with Ukraine calling the revocation a "strategic mistake" while signaling openness to dialogue about the contested history.
