Repeating the same thing it more or less words doesn't make it more true or false.
Russia has already lost, yes sure they have more troops, more rustly old tanks etc. etc. so maybe if they threw in all their crap, they gain a other 300m (that how much they gained in two months), but the bottom line is even in the area's that are Russian controlled they don't have the support of the population so they need to resort to repression and still the partisan movement wasn't stopped, it grew so long term even if Russia would win militarly which was a certain before all the support they(Ukraine) got, and is far from it now.
Calling a win for Russia is a far stretch, before Ukraine they where at least seen as a strong army, their S400 air defence systems have proven to be ineffective agianst Himars, there drone take-out system has been taken out... by a drone.
Their ''terminator'' tank developed for urban combat situations was pulled out of the first of such situation, Russia's economy is down deep and is going even deeper if all gas supplies to europe stop in Januari, Russia is defeated, they are just not ready to admit it.
