I think Odesa was always one of if not the main goals. I don’t think this ends until the Russians take it.
I think they want Odessa too, but I don’t think they care to go west of the Denipro River.
It’s on the other side of the Dnipiro River. Right now it’s impossible for them to take it. They were able to capture Kherson but couldn’t resupply it due to crappy logistics.
