Global advantage?! Did you mean significant, or overwhelming? Globally, Russia is in the 9th place behind Indonesia, Pakistan, Nigeria, Brazil, and Bangladesh; not to mention top 3: India, China and the USA. I won’t be surprised if by the end of 2024 it ends up somewhere between Ethiopia and Democratic Republic of Congo.
I’m glad that you finally acknowledged that Russia, as the original attacker, had suffered 5-10 time the losses of the defender - the Ukraine.
