A missile hit eastern Poland during Russia's mass strike. As this seems to be the first time when a missile hits NATO territory, this created a lot of reactions ranging from more cerebral to discussion of imminent article 5 triggering and NATO-Russia war.
According to The Guardian and also very briefly covered in this The Kyiv Independent article, many Western leaders convey the message that the missile is likely a Ukrainian air defense one. However, it is considered more of an accident and no one puts blame on the Ukrainian army, but the Russian army which lead to this:
Poland’s president, Andrzej Duda, has said there is no evidence to suggest the missile strike on Przewodów was an intentional attack or was launched by Russia
Jens Stoltenberg, confirmed that initial analysis suggested the incident was “likely caused by a Ukrainian air defense missile fired to defend Ukrainian territory” against Russian cruise missile attacks.
Joe Biden, also said the missile was unlikely to have been fired from Russia due to its trajectory.
However, president Zelenski has said he is convinced that the missile was not Ukrainian.
I am wondering about the rationale of Zelenski's declaration so shortly after the accident. Why not wait until the investigation is (almost) done? It is clear that no Western ally would put a blame on Ukrainian forces (basically nothing to lose here) regardless of the origin of the missile. However, such a declaration risks creating some communication inconsistency within NATO + the Ukrainian block.
