>Even satellite links can be altered, either you hack the satellite system or you intercept the signal at a higher altitude than the receiver is operating in.

Or, if the case of total war, you blow the freaking satellites out of space with missiles. Yes, I know space weapons systems are technically banned, but how long do you think a nation like the US, Russia, India, or China would put up with satellite controlled autonomous drones running roughshod over their sovereign territory before they just blow the satellites out of space?

Satellites can actually be destroyed using weapons that aren't in space. Back in 1985, the US had a F15 launch a missile which took out a satellite in orbit. China also recently destroyed a satellite with a ship-launched missile.

Yes, that's certainly possible too.
