We are kind of going in circles here, I think we can all agree:
That it would have best had Russia not invaded.
That the current best outcome would be the immediate cessation of hostilities.
But here we are, in this situation. Russias invasion (lets be honest, that's what it was) failed pretty spectacularly, they have adapted much like the Ukrainians did with the introduction of Himars. The Russians will continue to bombard infrastructure until Ukraine capitulates or until they no longer have sufficient SAM coverage, which will pave the way for them to use their very much still powerful air force to escalate until capitulation.
Either scenario is going to result in massive casualties and Russian control, does anyone have any realistic solutions that don't degenerate into WW3?
