I suppose. Would that really give you enough of an advantage to be worth the diplomatic cost, though? The difference between a semi-autonomous Predator drone and a fully-autonomous Predator drone in military terms doesn't seem all that significant.

Now, you could make a type of military unit that would really take advantage of being fully autonomous and have a real advantage, like a fully autonomous air-to-air fighter for example (not really practical to do with semi autonomous drones because of delayed reaction time), but it would seem like that would be much harder to hide.
