Any FPV or modified commercial drone are not doing long range strikes. They are used previously as you suggested, bombing nearby targets. Assisting troops, stopping vehicle assaults and hitting mortar positions etc.
Long range drones are essentially an unmanned remotely controlled plane, like a Predator.
These wired systems are on small FPV and commercial drones which without the use of repeaters etc aren't capable of 20km to begin with.
You can't guarantee that at all. You want it to be true because it serves your own ideas and rhetoric but in reality, you have no idea what he has, hasn't or will think about it.
That's a cool stance to take.
