ISIS seems to feed off the attention they get each they time, they post an execution video online. Following the reaction they got after posting the video of the Jordanian pilot's execution . . . they decided to burn five more other people in Iraq whom they accused of collaborating with Iraqi security forces. They also vowed to immolate more hostages. Sending ground troops IMO is the only way to defeat the beasts. If only the U.S was to lead by example . . .
