Irpin, Bucha, conventional weapons, even Russian, ones can be pretty devastating there are plenty of examples from this war. Anyway I can't be arsed arguing about, if they do use nukes it almost certainly brings Nato into it which will only make Russias position worse, so I doubt they will use them for tactical purposes, the biggest danger is if Putin decides to use them as a vengence weapon.im sure a conventional artillery round wouldnt devastate a 1 km area
