there's so many ways that this could easily spill over to something much bigger, scary as fuck.
What happens if Russia go full on with dropping missiles and flaming everywhere with their massive flame thrower in Kyiv, which leads to massive destruction of buildings, the government, and civilians...as many think could happen. What does Nato do then? Pretty much ran out of sanctions. And then over the years there is constant fighting in Ukraine which spills over into Modova, Belarus, and then the Baltics/Poland/Romania...what then?! Boom, that's what. Someone needs to take Putin out.
