Putin's incursion of Poland is the most significant attack since Ukraine war began

This incident, I would argue, is probably the most serious incursion. And in light of the ongoing conversations about ending the war in Ukraine and the so-called peace negotiations, I believe this is signalling that he [Putin] is not in a rush to end the war unless he gets the best deal. And quite the contrary, I think this proves that Russia's ambitions extend well beyond Ukraine."
