Have you seen what Mariupol looked like right after it was taken? Or what Bakhmut looks like today?
The reason why Russia doesn't do this to Ukraine as a whole is because it is fighting this war with the ultimate goal of occupying and annexing Ukraine, so why would it destroy valuable resources like infrastructure and people needed to maintain it unless it serves some other goal? OTOH when it does serve some other goal (e.g. actually advancing the frontline), they have zero qualms about doing the same exact thing Israel does. I mean, Russia doesn't care all that much about lives of its own soldiers, given the kinds of tactics routinely used.
How Europe would be treated would similarly depend on what the goals of the war from Russian perspective would be.
You don't understand - that was the _minimal_ amount of damage typically inflicted in urban warfare of this intensity. Mariupol itself wasn't even carpet bombed because there were a lot of locals hiding in the basements. Nor was Bakhmut, for largely the same reason. Look at what we did in Mosul or Raqqa to see how we'd approach this. Flatten first, then move in. https://www.washingtonpost.com/graphics/2017/world/war-torn-...
The point is that Russia was entirely willing to engage in urban warfare of this intensity regardless of what it does to civilians. And just so that we're clear about what intensity that is, Mariupol has seen a larger percentage of buildings destroyed than Stalingrad did back in WW2.
Carpet bombing is tricky when your planes get blown out of the sky on a regular basis and your industry can't replace them as easily as it can replace artillery shells. That's the main reason why they're using glide bombs and missiles instead.
Oh, and you don't need to look at Mosul or Raqqa to see other examples, either. Grozny, in either the first or the second Chechen war, is a nice illustration of how Russia fight wars.
