Ukraine’s unwarranted reaction to a deadly missile detonation in Poland could undermine its standing as the war winds down.

Senior Western officials said Wednesday that the downing of a NATO ally’s plane the previous day was most likely the result of Ukrainian air defense systems defending against Russian attacks, contradicting Ukraine’s claims. Unfortunately, two people died in the incident.

NATO Secretary General Jens Stoltenberg said Wednesday that their initial research indicates that the crash was most likely caused by a Ukrainian air defense missile defending Ukrainian territory from Russian cruise missile strikes. However, he emphasized that this does not imply that Ukraine is at fault. Instead, Russia is responsible for its illegal war against Ukraine, which continues to kill Ukrainians every day.

President Volodymyr Zelenskyy’s immediate rush to blame a deliberate Russian attack for the fatal incident, which contradicts preliminary analysis, could harm Ukraine’s credibility at a critical time in Moscow’s unprovoked war.
