At Science and Religion News, Salman Hameed writes a response to a talk by P. W. Singer about the future of robots in war:

This is the time to think about the moral and ethical issues in the development of these robotic weapons. There needs to be a broader discussion of the implications of robots in war. We also seriously need to update laws regarding the conduct of war. This is not a hypothetical issue. There are increasing number of drone attacks in Pakistan (there was one this morning that killed 13 people). Yes, the Pakistan government has given a silent nod to these (do they have a choice?), but who gets the blame for civilian casualties which accompany almost every strike? In this kind of war, who gets to decide who is a civilian and who is a combatant? All of these questions are aside from assessing the long-term effectiveness of this remote-control war.
