I believe that economically, socially, Russia is mortally wounded. Ukraine isn't in great shape either. But I don't see them ever quitting. Avdiivka fallilng will actually help Ukraine, with renewed support, than it will hurt in lost territory. Week after week, Ukraine delivers solid blows. Ships, oil refineries, factories, storage, planes, etc. Things that cost real money to be replaced. Real, real money and can't be done quickly. Russian resource output decreases. Harder to sell. It keeps adding up though we forget it.
