“Where did you dig up that bit of fiction?”
Your claim that Russia has air superiority is just fiction.
You said:
Russia shuts down areas of Ukraine for hours by doing flyovers of dangerous bombers (Air superiority)
And your link doesn't say that. It does however point out that "Russia's bomber fleet hasn't fired cruise missiles at Ukraine for a month, a sign its stocks are dwindling, UK intel says"
How does your claim of "air superiority" make sense if Russia's bomber fleet lacks ammunition to attack with?
