The absence of Russia's Air Force has been a bit of a mystery. Generally speaking, I think they will have a higher level of intellect - perhaps they are passively resisting the utterly ridiculous propoganda that "the Nazis are coming for us" and..."please launch your cruise missile at Ukranian cities to kill all the Nazis" b*******". Anybody with half a brain would realise they're being asked to committ unjustifiable war crimes and will be held to account.
