You think if someone was evil and willing, they’d design and launch a satellite designed to seek out another satellite and take it out of orbit in a way that causes it to drop randomly into the atmosphere?

All this instead of simply launching a satellite that does what they want? Or skipping the satellite and doing it with terrestrial solutions?

Some people’s threat models are very upside down.

A good shove being about 250m/s of delta v? Perhaps more to be certain of where you’re landing. Not exactly trivial or stealthy.

Why not just load up some nuclear waste on your “shoving device” and launch that exactly where you want?
