Terrorist threats have become more complex and diverse than before. On June 6, , an American Reaper drone killed four Islamic State fighters near Bani Walid, Libya, about 110 miles southeast of Tripoli, Libya’s capital. A week later, another Reaper killed a Qaeda operative 50 miles southeast of Bani Walid.
