Frankly speaking I believe that if Russia, had envisaged that this war will drag to this point and that it will cost them so much both economically and in human resources I'm sure that they would have thought twice before hastily invading Ukraine. They definitely thought that the invasion would be a walk in the park but see where it has landed them, Ukraine's continued resistence have kept the war going, from what I can see the both sides are not ready to retreat.
Russia's pride is on the line and they wouldn't want to back down at this point so it means that they are prepared to sacrifice other sectors of their economy to fund the war, same with Ukraine, who will not bow down despite the harsh reality of the war on their economy. I hope that they can reach an agreement sometime soon because they cannot continue like this unless they want to go on until one of them will give up.
Populism, corruption and total lies in the russian government have caused such "blunders". Well, and inflated self-esteem - just remember how they constantly put on display that Russia is supposedly "the second army of the world", that it has "unparalleled armaments", "the strongest economy" and other propaganda nonsense. And it played against them - they deceived themselves.
The army turned out to be just "cannon fodder" unable to break a small and poorly armed army. The "unparalleled armament" also turned out to be a fake. The strongest economy? It's funny - in 4 years Russia has lost its strategic buyers in the EU, lost its markets FOREVER, became a raw materials appendage of China and India. Russia is pathetically begging for manpower from North Korea, and Shaheds and missiles from Iran ! Isn't that a success ?

There is still a general mobilization and collapse of private business, global resolution of key industries (oil and gas sector) ahead.
It is not the “pride of Russia” at stake for a country that has no honor to be proud of ! At stake is the life of the Kremlin Fuhrer and Rashism as an ideology !
He will kill millions more of his citizens, destroy the economy of his country, just to save his own skin and try to realize his painful complexes, which he earned when small but proud Ukraine gave a giant empire a kick in the teeth !
