Robot soldiers are no longer just the stuff of sci-fi fantasy. As technological warfare expert P.W. Singer explains in his new book, Wired For War, some military tasks previously assigned to humans are now being handled by machines.
But, says Singer, the new technological battleground — in which robots fly spy planes and search out IEDs — raises a host of ethical and legal quandaries.
Singer is a senior fellow at the Brookings Institution. His previous books include Corporate Warriors and Children at War.
