I think some of the “Oh please, make this stop!” ideas are simple wishing.
Putin wants ALL of Ukraine. He wants a puppet in place, just like in Belarus, so he has an eastern buffer of “independent” dependencies that he fills with Russian military bases.
He wants ALL of the northern coast of the Black Sea, so his Med/MidEast fleet has unfettered access and US warships, etc. have to steer much clearer of Sevastopol and Odessa.
And, while he’s at it, he’d like the Baltic ELL states back as dependencies, so he has a land bridge to Kaliningrad, his only year round ice free port in N. Europe, and their coastlines.
This is not his endgame, it’s his opening gambit!
