The Pros and Cons of a Ukrainian Operation

The offensive should be gauged against three broad criteria. The first is if Ukrainian forces are able to liberate a significant amount of territory by significant? It doesn't have to be something along the lines of Harkovar-Hurson, but it has to be substantially different than what we've seen over the course of fighting last six months. That would mean breaking through to some kind of notable objective and achieving something beyond just limited gains.
