The June 2015 issue of our journal Perspectives on Terrorism begins with an article by Ali Fisher that explains how ISIS with its Swarmcast technique manages to outwit those who try to contain its propaganda on the Internet. One group that has been vulnerable to ISIS’ propaganda are Muslim women in Western diasporas, although women have more to lose from ISIS than most other groups. This paradox is the subject of Anita Peresin’s article.  What has contributed much to the recruiting success of ISIS and other jihadists groups since 9/11 are the strategic mistakes made by those who oppose them. Scott Englund touches on this issue in our third article. ISIS is still puzzling policy-makers and one reason for this is that they cannot decide on what exactly the danger is. Boaz Ganor offers greater clarity by posing and answering four key questions in his Policy Brief.
The Policy Brief section also features an interview by Brian G. Williams with Lt.-Gen. David Deptula, a former US Air Force officer involved in the use of drones for countering terrorists. While collateral damage is much lower than from other instruments of war, drones have many critics. As customary, this issue contains book reviews and bibliographies from the hands of Joshua Sinai, Judith Tinnes and Eric Price.
