U would fold like a broken beach umbrella without West
Russia's performance in Ukraine, their inability to shut down Ukrainian aircraft and air defenses to attain air dominance and their inability to suppress Ukrainian artillery despite a significant artillery advantage has been a rather harsh indicator that Russia's military has a lot of tactical, operational, and even strategic shortcomings.
I don't think you really understand, or maybe you just can't accept, how absolutely terrible Russia's military performance has been this war. They have a massive equipment advantage over Ukraine in many important categories (artillery and airpower stand out but there are others as well) and this is all they have been able to accomplish in half a year. Russia should have been able to win with the type of advantages they had. That is why everyone thought they were going to quickly win the conventional phase of the war when it first started. Right now no one who isn't deluded is telling themselves, "Wow, Russia sure has shown how strong and capable they are in Ukraine!"
