A year after Obama laid out new conditions for drone attacks around the world, U.S. forces are failing to comply fully with the rules he set for them: to strike only when there is an imminent threat to Americans and when there is virtually no danger of taking innocent lives. Although Obama promised greater transparency in his speech at the National Defense University, U.S. lawmakers are increasingly critical of the secrecy surrounding the operations. There are growing concerns in Washington that the net effect of the targeted-killing program may be counterproductive. [Obama] is showing no sign of relinquishing what has become his counterterrorism weapon of choice since he took office in 2009. Drones are spreading to new areas ... in far-flung places like Somalia and in Nigeria. Here we are, a year later, asking 'what has really changed?'" said University of Notre Dame law professor Mary Ellen O'Connell, a leading expert on extrajudicial killings who has testified before U.S. congressional committees. "The drones are still flying and the president still sees the attractiveness of this cold and antiseptic means of killing." Obama's vision of shifting control of the drone program from the shadowy paramilitary arm of the Central Intelligence Agency to the more publicly accountable Pentagon is moving at what one national security source described as a "glacial pace." The Pentagon's Joint Special Operations Command is widely believed to have been behind the December 12 drone strike in a remote part of Yemen that hit a convoy later identified as a wedding procession, killing 15 people.
