I doubt Russia would be using S-300s, a SAM platform, to attack ground targets if their economy was booming and they were doing fantastically under sanctions. There's been big dollar values thrown around for Ukraine aid, but that's just the paper numbers for what the equipment Americans have been giving them is 'worth'. At the end of the day, America has been doing nothing but giving Ukraine old trash from stockpiles that sat unused for decades. Russia is having trouble fighting a soviet bloc country equipped with late 80s and early 90s US technology. Imagine how horrible they would do in any modern war. HIMARs are from the 90s. Javelins are from the 90s. Hell, the stinger missiles we've given them started production in 1981! Russia is having trouble fighting a soviet-tier military equipped with the same stuff the US was giving Afghanistan in the 80s! It's comical to watch how much Pentagon analysts overestimated Russia's abilities. It's like the whole country's military doctrine froze in the mid 80s and never evolved further.
The most surprising thing at this point is that Putin hasn't managed to fall out of a window after causing all of his little oligarch buddies to have their pristine lifestyles rudely interrupted.
Everyone knows Russia is a shithole country. Even Russians admit it, but still, they prided themselves on a supposedly well equipped and powerful military. Now, they don't even have that. Sad!
