Th Russians didn't go in with the original intent of shock and awe and bombing the Ukrainians to the stone age. You do realize that, right? They originally went in hoping to get Kyiv/3elensky to capitulate quickly. That didn't work. Then when the UK and US shot down the deal that they were going to have in late March, they refocused. After the Kerch Bridge and Nordstream bombings, the Russians finally turned up the heat to where the American would have to an extent.
The Russians are now, sadly, put in a position where the Kyiv regime and the US are running waves of men into the meat grinder and having them take these ridiculous stands when they should be surrendering or retreating.
