The question of how positive/negative one is is highly dependant on the belief on Russian political/military aims of this war.
If one thinks that Russia wanted to take over Ukraine from day 1 and destroy Kiev, kill Zelensky, install a puppet government, well, they are failing. In fact, they are a laughing stock.
If one thinks that the real aim might be to call the western NATO bluff and prevent that from happening, it looks like they will succeed. They will also possibly gain the Donbas region and connect it with Crimea. Maybe Putin thinks that losing numerous planes, helicopters, countless tanks is a price worth paying.
I read an interesting review saying that Russia's political aims highly outweigh the military ones in this conflict.
The real tragedy of this war is that to succeed in these aims, whatever they are, thousands of innocent people and young soldiers will die.
