Supporters of the Islamic State (IS) took to Twitter to respond to President Barack Obama’s speech wherein he outlined his approach for eradicating the group.

The Islamic State's phenomenal ability to entice young Western Muslims to the battlegrounds of Syria has relentlessly made headlines throughout 2014, with the activities of these fighters raising threat levels around the world. As noted recently by SITE Intelligence Group Director Rita Katz, jihadi groups in Syria go to great lengths to target propaganda at Westerners and to encourage disaffected and idealistic young Western Muslims to leave their home countries for battle.

Douglas McAuthur McCain, an American Islamic State (IS) fighter, was reportedly killed by the Free Syrian Army on August 25, 2014.

Islamic State (IS) supporters are using captured American journalist Steven Sotloff, whom the group threatened to behead upon further intervention from the US, as a threat toward the US using a new hashtag, "#StevensHeadinObamasHands."

The fighter in the Islamic State's (IS) August 19, 2014 beheading video of James Foley has prompted intense reactions among Westerners. As the unidentified fighter's nationality was confirmed to be British, Prime Minster David Cameron cancelled his vacation to assist in what has quickly become an international investigation to identify this man. But while the execution marks a newly elevated step by IS to challenge the West, the fighter's British nationality should be of no shock.
