Ignoring regime change for a minute, the two big levers EU/USA seem to have is sanctions and proxy war (by funding and equipping Ukraine). Anything else like bombings are immediately off the table due to nuclear deterrence.

If we take minimizing civilian casualties as the goal, is your position that equipping Ukraine and leaving Russia alone otherwise is the best option?
