Attack of the Drones

Since taking office, President Barack Obama has unleashed five times as many drone strikes as George W. Bush authorized in his second term in the White House. He has transformed drone attacks from a rarely used tactic that killed dozens each year to a twice-weekly onslaught that killed more than 1,000 people in Pakistan in 2010. Last year, American drone strikes spread to Somalia and Libya as well.

The first drone strike under the Bush Administration was in Yemen.
