We will never learn of satellite war.... we will never hear about attack sat drones that take out other sats but it happens regularly... think of the plane that was in orbit as 3 years, which was the Jimmy Carter of space (I hope you know that ref) ((if you dont, then you dont know shit))
That's paranoid nonsense. Attack drones don't regularly take out other countries' satellites. There is no way to hide such activity in orbit and it would be obvious to everyone, including amateur civilian observed.
Here's the real situation. All of the superpowers have some level of kinetic anti-satellite weapons capability and have conducted a few isolated tests against their own satellites. The X-37B drone spaceplane may have some anti-satellite role but has never been used operationally in that capacity.
