Polish Foreign Minister Radosław Sikorski described the attack as an attempt to probe NATO defenses and test the alliance’s commitment to protect its eastern flank. Meanwhile, NATO has announced the launch of the Eastern Sentry deterrence initiative, with plans for more integrated air defense, intelligence sharing, and new assets. If the West fails to credibly deter further Kremlin escalations, this would have potentially disastrous consequences for international security. This combination of intensifying economic pressure on Russia and increased military support for Ukraine could set the stage for a ceasefire agreement. Putin’s latest escalation in the skies over Poland is an unmistakable signal that NATO’s credibility is under threat.
