One of the most important aspects of what I share re: Ukraine, is not overly focusing on the horrors or losses of land, but talking of resilience and victory.
My grandfather told me of living in London during the Blitz, where one building in three was destroyed in under a year. This is not that.
So, I say to Ukrainians: as bad as things are, if you keep fighting, the Russians will inevitably leave Ukraine, and you will undoubtedly win, with your cities intact. Everything will be alright.
