ASAT missiles are only suitable for low earth orbit, you’d need a rocket about the size of a falcon 9 to reach GEO where Intelsat was sitting. Think people might notice that. Wouldn’t need the satellite to be on a suicide mission, could just slap a gun on it like the good old days.

They have one sigint satellite Olymp-K creeping around up there, why not a second that doesn’t have a Wikipedia article
