I'm sure that one important topic discussed was how the greater public may react to different methods of using drones compared to boots on the ground or planes in the air. Since you essentially have a piloted plane where the pilot can't die or be captured the public may view various uses with passive interest.Historically we have seen that the greater public in any society rebels or gets upset when they are directly affected. This affect may be financial or social. If a government might use a drone to further its objectives without bringing financial or social harm to a certain percentage of its citizens, then the use of drones would be warranted even if the use were not ethical.
The conversation the media needs to present then, to any given society, is to the question of the ethicality of drone use for each given scenario.
