I wouldn't go too far. Cadence of President Kaczynski ends this year, and he would be probably beaten in the next elections. Moreover too many people died in this accident and any justified suspicions might lead to war. The fact it happened in Russia don't make it's not coincidence. But that's right, Mr. Kaczynski was known for his anti-kreml policy.

any justified suspicions might lead to war.

What, Poland would declare war on Russia? I have my doubts.

Not directly. But if there were justified suspicions, it would mean someone having a reason to say "agents of country X decimated the government of an EU/NATO country". It's unlikely there would be no response to that.

Assasination the President and many officials including all military leaders from coutry which is a member of NATO might worsen current not good relations between the coutries. Plus honour and polish national pride. But there's any reason it's not an accident at all.
