As you probably already know, the United States has increasingly relied on drones, or unmanned aerial vehicles, to carry out warfare in recent years.  Drone attacks have been particularly popular under President Barack Obama's administration.  According to the New America Foundation, there were 43 drone attacks between January and October 2009 (right when Obama took office), compared to just 34 in all of 2008 (when George W. Bush was still in office).  The Obama administration has shown no indication that it will halt the use of drones, which are responsible for the deaths of many alleged terrorists.
