But didn't the war in Ukraine change that?
From the beginning of the war Russia has encountered great difficulty, logistics, quality of equipment etc..
It could be explained by the fact that Ukraine has shown a heroic resistance that Putin had certainly not foreseen. Of course we can not ignore the fact that the Russian military difficulties today are due to the fact of economic sanctions, American aid whether it is at the economic level, equipment, intelligence etc..
I do not know if Russia will win this war or not. Besides, to know if Russia will win it would be necessary to know what its main objectives are.
But it seems to me that the Russian military power has been quite overestimated.
