Russia couldn’t go against fucking Ukraine with the help of the entire NATO (including US) stockpile backing it up.
Imagine what those early days would have looked like without MANPADs and man portable anti tank weaponry. Imagine the rest of the war without tanks and artillery systems and air defense. It wouldn’t have lasted long.
The narrative that Russia just sucks is prevalent and fun, but the reality is that it only sucks when the entire West works together to counter it. Fracture that support and it’s a lot more formidable. And it’s learning and becoming much more battle hardened.
