Again what I brought up in earlier posts russians are inept, terrible equipment, will not last a month and so on. Here we are one year of hell down the line.
Russia has waged war at terrible cost to itself, sustained war at terrible cost, unlike some I'm under no delusion as to how long they can continue it, the potential for growing into this war if given time - but that has another edge to it - conceding Russia the Donbass won't end this situation, it might temporarily pause it, but it will only embolden Russia to push again, and likely better prepared next time.
