All this has been thrashed to death before, the security risks and considerations far outweigh any advantage to going pilot less. A dedicated suicide bomber and his mates could take over a ground control station, causing chaos, or they could simply transmit rogue signals that block the genuine ground to air signals, also causing chaos. The concept is a non starter due to security, regardless of technical advances.
The USA should know better than anyone, if they check their inventory of UAVs they will be well aware that they have lost a lot of UAVs and most are not through enemy action, they are light years away from an acceptable level of reliability.
