Abstract:
The March issue focuses in particular on the drone threat. In the feature article, Don Rassler and Yannick Veilleux-Lepage examine the evolution of terrorist drone usage and forecast its future trajectory in light of the tactical and technological innovations emerging from the Russo-Ukrainian War. They write that “the conflict has become a critical ‘innovation hub’ for drone warfare, accelerating advancements in the scale, speed, and range of drone operations. These developments are not only transforming the modern battlefield but also creating new opportunities for violent extremist organizations (VEOs) to enhance their operational capabilities.” They assess that “in particular, the war has normalized large-scale drone deployment, demonstrating the feasibility of launching coordinated drone swarms and phased attacks capable of overwhelming existing defenses” and note that the potential future pairing of high-speed First-Person View (FPV) drones with emerging technologies such as AI-assisted targeting “could significantly increase the precision and impact of future attacks.” In a similar vein, Jake Dulligan, Laura Freeman, Austin Phoenix, and Bradley Davis, in assessing the threat posed by commercial drones, write that the biggest concern “is that drone swarms could dramatically increase the impact of bad actor drone operations, be it kinetic strikes, ISR, or psychological warfare.” This month’s interview is with Dr. Christian Klos, the Director General of Public Security at Germany’s Federal Ministry of Interior and Community. He says that “when it comes to the external threat, I would agree with the assessment that ISIS-K is in Germany as well. What we observe from the intelligence side is that there are clear indications that the group intends to conduct attacks in Europe, and this can also include Germany and therefore we are very much aware of this threat, and we have seen also travel activities. So, it’s not just some minor indications.” Aaron Zelin assesses the new Syrian government’s efforts to counter the Islamic State, Hezbollah, and the captagon trade. He writes: “Unlike the Assad regime—which did little to fight the Islamic State, was closely aligned with Hezbollah, and produced captagon on an industrial scale—HTS in its guise as the new government of Syria is taking on these challenges assertively, and has a significant track record in doing so previously. Not only are these efforts a benefit to Syrian society and the security and stability of the country, but they also align with the interests of the United States and U.S. regional allies.” Alexandre Rodde and Justin Olmstead examine the evolution of vehicular ramming attacks and prevention efforts. They write that “when it comes to indicators and warnings of future attacks, the demonstration effect created by high-casualty vehicle-ramming attacks has in the past seemingly produced a surge in copycat attacks, which means the security agencies should be particularly vigilant given the recent uptick in high-profile attacks, including the New Orleans attack.”

Abstract:
Six months have now elapsed since the events of January 6. This issue of CTC Sentinel focuses in large part on the evolving threat of extreme far-right violence around the world. In the feature article, Graham Macklin examines in detail the thwarted October 2020 conspiracy to kidnap Michigan Governor Gretchen Whitmer. He writes that the plot “highlights how anti-government ‘militias’ have continued to adapt and evolve, exploiting conspiracy theories and deliberate disinformation surrounding the pandemic, to remold traditional grievances about the ‘tyranny’ of the U.S. government.” In a wide-ranging interview, Deputy to the Under-Secretary-General Raffi Gregorian, the director of the United Nations Office of Counter-Terrorism (UNOCT), says the United Nations needs to counter extreme far-right violence around the world. “It’s worth reflecting about the origins of the United Nations as a group of allies fighting Nazis,” he states. “We ought to be doing this. We have a legal basis to do it. It would be nice to have a clear political signal to do it. I think we’ll get it. And I think we’ll get it because the countries that are most afflicted with it right now are ones that are also very interested in doing something about it.” The reporting of Yassin Musharbash and a team of his colleagues at Die Zeit has shed significant light on the globalization of the violent far-right. In an article that outlines and elaborates on this reporting, Musharbash writes that “right-wing extremists today, in many cases, no longer subscribe to the narrow concept of nationalism but instead imagine themselves as participants in a global struggle against a global enemy.” Matthew Kriner and Jon Lewis examine the Proud Boys, a violent far-right group alleged to have played a significant role in the U.S. Capitol siege. They write that the group has “continued to mobilize, sometimes armed and violently, in response to the continued disinformation narratives related to the ‘Stop the Steal’ movement, vaccines, and more, appearing at more than 20 events in 13 cities since January 6.” Milo Comerford, Jakob Guhl, and Elise Thomas profile Action Zealandia, outlining how the extreme far-right group fits into a “small but persistent far-right extremist ecosystem” in New Zealand and its “growing links with violent extreme far-right movements internationally.” This September, to mark the 20th anniversary of 9/11, the Combating Terrorism Center will be publishing a special issue of CTC Sentinel on the evolution of the global jihadi threat.

Abstract:
The violent storming of the U.S. Capitol on January 6, 2021, has heightened concerns about the threat posed by far-right extremism in the United States. In examining the wide range of terrorism and counterterrorism challenges facing the incoming Biden administration in this month’s feature commentary, Bruce Hoffman and Jacob Ware write that “the January 6 events at the U.S. Capitol offered a stark, frightening picture of the powerful forces fueling a conspiratorial mindset eschewing both the country’s foundational democratic values and the rule of law” and “serves as a salutary and timely reminder of the danger of potential violence to come.” Given the continued threat posed by “a stubbornly resilient Islamic State and an implacably determined al-Qa`ida,” they write that “it may be that as the United States and its allies enter the third decade of war against international salafi-jihadi terrorism, we need to recalibrate our immediate expectations away from ‘winning’ and ‘losing,’ toward ‘accepting’ and ‘managing’ this conflict. Such an admission would not be popular, but it would be a fairer reflection of the current state of the fight against terrorism, and a more honest prediction of what to expect over the next four, or more, years.” Our interview is with David Lasseter, the Deputy Assistant Secretary of Defense for Countering Weapons of Mass Destruction. He notes that “advances in synthetic biology and other related biotechnologies hold the potential for both promise and peril in their application. And so we’ve got to be cognizant of how such technological shifts can alter the threat landscape [and] impose new defense and security challenges. We’ve heard it said that biological weapons are ‘a poor man’s nuke,’ given the potentially enormous impact of their usage. I think COVID-19 has further accelerated this mindset. The U.S. has had a watchful eye on bio threats and has elevated bio threats as a core national security priority over the past several years.” In an assessment that has far-reaching implications for the U.S. military mission in Afghanistan, Jonathan Schroden finds that if the United States were to withdraw the remainder of its troops from the country, the Taliban would have “a slight military advantage” over Afghanistan’s security forces, “which would then likely grow in a compounding fashion.” Nodirbek Soliev examines the Tajik connection in an Islamic State plot against U.S. and NATO air bases in Germany thwarted in April 2020.

Abstract:
The final two years of this decade witnessed a wave of far-right terror attacks around the world, including the October 2018 synagogue shooting in Pittsburgh, Pennsylvania; the March 2019 gun attacks on mosques in Christchurch, New Zealand; the April 2019 Poway, California, synagogue shooting; the August 2019 attack targeting the Hispanic community at a Walmart in El Paso, Texas; and the October 2019 Halle, Germany, shootings, in which a synagogue was targeted. In our feature article, Graham Macklin examines the El Paso attack, which he assesses was “part of a chain reaction fomented within the violent sub-cultural online milieus of right-wing extremism.” He writes: “This digital ecosystem is fueling a cumulative momentum, which serves to lower ‘thresholds’ to violence for those engaged in this space, both in the United States and elsewhere, as one attack encourages and inspires another.” The Halle shootings appear to have also been part of this chain reaction. In a case study, Daniel Koehler writes that the far-right extremist who carried out the shootings in the eastern German town “appears to be mainly a copycat attacker inspired by previous incidents” such as the shootings in Christchurch, Poway, and El Paso. Koehler writes: “The Halle attack reflects and evidences several trends, including the internationalization of right-wing terrorism and lone-actor terrorists fashioning their own weapons. The attack stood out because it was the first time a terrorist appears to have used homemade firearms.” Our interview is with Lieutenant General John “Jack” Shanahan, the director of the Joint Artificial Intelligence Center at the U.S. Department of Defense. In that role, he is responsible for accelerating the delivery of artificial intelligence-enabled capabilities, scaling the department-wide impact of AI and synchronizing AI activities to expand joint force advantages. Tore Hamming draws on court documents from a recently completed trial to examine the 2016 Copenhagen ‘Matchstick’ terror plot. The failed conspiracy saw an Islamic State ‘virtual planner’ based in Syria connect and direct two Syrian refugees living in Sweden and Germany. The case provides insights on the evolving jihadi terror threat in the West and its transnational dimension. Hamming writes: “The plot presented obvious challenges for Western security institutions. Central to its planning and execution were the virtual planner and the availability of instructions on how to construct explosives.”

Abstract:
In an extensive interview, General John W. Nicholson, commander of Resolute Support and U.S. Forces-Afghanistan, stresses the importance of preventing the country from again becoming a platform for international terrorism, noting counterterrorism operations have almost halved the fighting strength of the Islamic State’s local affiliate. He also outlines the ongoing effort to empower Afghan efforts against the Taliban, saying: “They’re at a bit of a stalemate. The government holds about two-thirds of the population. The enemy holds a solid 8 to 10 percent. … We think [if] we get to about 80 percent or more, we start to reach a tipping point where the insurgency becomes more irrelevant.” Our cover story by Georg Heil focuses on the deadly truck attack this past December in Berlin by Anis Amri, a Tunisian extremist suspected of links to Islamic State operatives in Libya. Investigations have made clear the danger posed by the radical network he belonged to in northwestern Germany led by an Iraqi preacher named Abu Walaa. It is believed to have recruited dozens to travel to join the Islamic State, communicated extensively with Islamic State operatives in Syria and Iraq, and encouraged attacks on German soil. Heil argues the high level of interconnectedness between these radicals in Germany and the Islamic State has potentially grave implications for European security. Aymenn al-Tamimi looks at the implications of the recent realignment of rebel and jihadi groups in Syria, which created two potentially conflicting power centers revolving around an enlarged Ahrar al-Sham and Hay’at Tahrir al-Sham, a new al-Qa`ida-aligned umbrella grouping. Robin Simcox finds Islamic State plots by pre-teens and teens are increasing in the West, with plotters in contact with the group in a majority of such cases. Shashi Jayakumar examines the growing Islamic State threat to Southeast Asia, arguing the group may pose as big a threat in the future in the East as in the West. Andrew McGregor warns growing clashes between Fulani Muslim herders and settled Christian communities in Nigeria could be exploited by terrorist groups and potentially destabilize the entire Sahel-West Africa region.

Abstract:
This report contains an analysis of over 4,600 unique Islamic State personnel records that were produced by the group primarily between early 2013 and late 2014. The importance of this data for understanding the Islamic State and, in particular, the foreign fighter flow, cannot be overstated. To put it simply, it is the largest cache of primary source documents produced by the Islamic State available in the open-source as of this date. These particular documents were acquired by NBC News from an Islamic State defector and subsequently provided to the CTC (and other entities). This report provides a window into the organization’s global workforce, revealing information about foreign fighters’ countries of origin, citizenship, points of entry into Syria, marital status, skills and previous occupations, education levels, religious knowledge, fighting role preferences in the group, and previous jihadist experience. In addition to analyzing the data at the macro-level, the report also highlights numerous anecdotes of individual fighters. Taken together, the analysis in this report reveals an organization that is attempting to vet new members, manage talent effectively within the organization, and deal with an incredibly diverse pool of recruits.

Abstract:
In early October 2016, the group that calls itself the Islamic State killed two Kurdish soldiers with an explosive device hidden inside a drone. While terrorist groups have long had a fascination with drones and experimented with their use, the incident was a first for a terror group, and it potentially represents the leading edge of a wave of similar incidents that could follow in the months, years and decades ahead. Much has been made of the threat of terror use of drones, but little empirical and historical work has been done to support our understanding of this phenomenon and its evolution. This report seeks to address this gap by providing a review of, and framework to situate, cases in which terrorist entities have either shown a substantive interest in drones or have used them. It evaluates both individual use cases and the activity of groups that have used drones frequently enough to constitute their having a “program.” These cases are then complemented by a review of the creative ways that private citizens have used drones, in order to provide decisionmakers with a firmer baseline of both demonstrated terror capability and what lies within the immediate realm of possibility, given what has already been achieved by others. This report also includes an overview of new technologies that are likely to further complicate the scope of this developing threat.
