I don't think it's Putin. It's just an accident. They were dumb enough to stick all government officials plus the president on one plane.
I don't give a shit that he's dead tbh. He was a lousy human being. He despised gay people and tried to stamp them out, so fuck him. It's so incredibly fake what's happening now in Poland. Everyone is suddenly devastated that he's dead while before 80% of the population mocked him.
