Cover Story Overview

After a respite from mass-casualty terrorism for more than a decade, the United Kingdom this past spring suffered three such attacks in the space of just 73 days, making clear it faces an unprecedented security challenge from jihadi terrorism. In our cover article, Raffaello Pantucci outlines what investigations have revealed so far about the March attack on Westminster Bridge, the bombing at a pop concert in Manchester in May, and the June attack on London Bridge and Borough Market. The early indications are that the Westminster attacker, Khalid Masood, had no contact with the Islamic State and the Manchester and London Bridge attackers were, at most, loosely connected to the group. The current threat environment, Pantucci writes, continues to be mostly made up of individuals and smaller scattered cells planning lower-tech attacks with very short planning and operational cycles—sometimes remotely guided by the Islamic State—rather than cells trained and dispatched by the Islamic State to launch large-scale, Paris-type attacks, but this could change as more British Islamic State recruits return home.

Our interview this month is with Edward You, a Supervisory Special Agent in the Biological Countermeasures Unit in the FBI’s Weapons of Mass Destruction Directorate. While the full liberation of Mosul last month effectively ended the Islamic State’s caliphate pretensions, Michael Knights warns the Islamic State and other jihadis are already bouncing back in several parts of Iraq and more strongly and quickly in areas where the security forces are either not strong enough or not politically flexible enough to activate the population as a source of resistance. As the Islamic State transitions from administering territory to a renewed campaign of terrorism and insurgency, Charlie Winter and Devorah Margolin examine the Islamic State’s apparent lifting of its moratorium on using women as suicide bombers. In a commentary, Aaron Brantly argues that creating back-doors in encryption, or banning it, would create significant societal costs without stopping terrorists from accessing the technology.
