Sure, but autonomous control systems for cruise missiles and attack drones are improving rapidly. They aren't quite as good as remote human pilots but adequate for most missions except interdiction or close air support. So higher latency might not be a problem if satcomm is only needed for strike coordination.

The more significant technical problem with geostationary satellites is you need a much higher gain antenna. Tough to incorporate that into a small drone design. The Starlink/ Starshield terminal is a marvel of compact efficiency.
