The Russians do not control the sky over Ukraine.
Certainly, they have control over much of the air, much of the time.
They do not control low earth orbit. The Ukrainians (and everyone) sees almost everything they do.
The Russians see much of what Ukrainians do, but it is more difficult for them to separate the civilians from the military. That gives the Ukrainians an advantage.
We will not know how this works out for a while, and we will not know much of the details for years.
The thing to bear in mind is that Russia is only fighting in certain areas. They are not invading to occupy. They are taking down the globalist cabal that has a stranglehold on the Ukraine. They have specific targets such as Mauripol where the control and command center of the Azov brigade/ Khazarian mafia is located. Other targets are the NATO military bases and the bio weapons labs. Varying reports say the Russians captured either a child trafficking ring or dirty bomb production site at Chernobyl. Whatever it was it wasn’t good. The Russians are flying wherever they want to fly in the Ukraine and their ground forces are methodically carrying out their strategic ground operations. Personally I expect to see a peace agreement very soon.
