Russia signed the 1967 Outer Space Treaty (OST) in 1967, this may be a treaty violation of this or other treaties, something like that or retaliation regarding it may be possible.
You can hack the satellite, or use other electronic warfare options to jam or interfere with it's operations.
You can shoot it down with a missile.
The X-37B is in space right now and interfering with space assets is a pretty obvious possibility for why it exists at all, but it's secret so nobody says these things.
If you start shooting down stuff in orbit, it'll invite retaliation, but even without retaliation there's a huge risk of a Kessler syndrome (especially with all the stuff that SpaceX has put into orbit in recent years).
> You can shoot it down with a missile.
Obviously a bad idea, but frying it with some sort of high powered electromagnetic pulse would seem the smartest option with plausible deniability.
I wonder if the US already has such weapons in orbit.
So Russia may be in violation of a treaty, treaties. I'm shocked.
