East and South Ukraine where the war is at its heaviest is surely where the most opportunity mentally to get an edge is now for Ukraine.
They appear to be more the willing to do so under such circumstances too:
Suffer now and when the new weapons signed off by the EU and NATO arrive, more tools then.
East and South Ukraine ultimately, and Kyiv, is likely where Russia will target everything moving forward as the reality is Russia are not as strong as they brainwash their people on TV about. Those days are gone now.
