The Defense Department's policy for autonomy in weapon systems may appear to reflect caution, but it allows the Pentagon to fund, test, buy, and use technology that could target and kill by machine decision.
Chemical weapons and national security experts assess the situation in Syria and suggest ways in which the United States and the international community might proceed, in light of what would—if proven true—be the most extensive use of chemical weapons in the Syrian uprising.
