On March 5, the United States used unmanned drones and manned aircraft to drop bombs on a group of what it described as al-Shabab militants at a camp about 120 miles north of Mogadishu, Somalia, killing approximately 150 of them. The administration claimed that the militants presented an imminent threat to African Union troops in the region with whom US advisers have been working, although it produced no evidence to support the claim. The news that the United States had killed 150 unnamed individuals in a country halfway around the world with which it is not at war generated barely a ripple of attention, much less any protest, here at home. Remote killing outside of war zones, it seems, has become business as usual.

This is a remarkable development, all the more noteworthy in that it has emerged under Barack Obama, who came to office as an antiwar president, so much so that he may be the only person to win the Nobel Peace Prize based on wishful thinking. Our Peace Prize president has now been at war longer than any other American president, and has overseen the use of military force in seven countries--Afghanistan, Iraq, Syria, Pakistan, Libya, Yemen, and Somalia. In the latter four countries, virtually all the force has come in the form of unmanned drones executing suspected terrorists said to be linked to al-Qaeda or its "associated forces."

That an antiwar president has found the drone so tempting ought to be a warning sign. As Hugh Gusterson writes in Drone: Remote Control Warfare:

If targeted killing outside the law has been so attractive to a president who was a constitutional law professor, who opposed the war in Iraq from the very beginning, who ended the Central Intelligence Agency's torture program, and who announced his intention to close the Guantanamo Bay detention camp on assuming office, it is unlikely that any successor to his office will easily renounce the seductions of the drone.
