Exactly! Whether it was a Russian missile or a Ukrainian one is irrelevant. This was undoubtably an error and not a deliberate attack from either side.
No, it was a deliberate Ukrainian attack, third of its kind. Whatever other explanations make no sense. There were no Russian missiles to chase in Poland.
I will say also, if someone had shelled your nation for
over a month now, what would be your first thought if a
missile went astray, even if it was your own missile by
mistake?
