Because terrorist groups like al-Qaeda and Islamic State in Iraq and Syria (ISIS) have been successful in adapting and innovating in response to counterterrorism measures, it is important to develop a flexible, responsive sanctions regime similar to the 1267 regime, but that can include new organizations and bodies designed to keep it relevant and applicable— and any new regime considered for violent far-right groups should be similarly flexible—both in terms of the various measures employed, but also concerning the individuals and assets to be targeted. • Due to ISIS’ relatively unique ability to capture and administer large swaths of territory as it built a proto-state and diversified its funding portfolio, it is somewhat difficult to assess how effective sanctions were against the group. • If certain terrorist threats concern only a limited number of states—for example, the rightwing threat is likely to be more prominent in North America, Europe, and Oceania, though it certainly exists elsewhere—there may be less of an impetus, or little sense of urgency, for states outside of those immediately impacted to act. In that sense, the threats posed by al-Qaeda and ISIS) were more transnational, and as a result, generated global consensus more easily. Therefore, it will be crucial to work toward creating consensus, as well as to explore other applications of sanctions to counter the violent far-right threat. • One of the primary challenges to evaluating the impact of sanctions against terrorist groups is the lack of an effective assessment framework, in addition to data gaps. The sensitive nature of data related to terrorism and counterterrorism is one of the primary reasons why it has been difficult to provide a comprehensive assessment of the United Nations’ overall impact in this area. • Recommendations include: focus on tailor-made sanctions regimes that can adapt to the terrorist threat, considering both multilateral and national options; establish metrics to assess implementation and impact of sanctions regimes; and invest in international cooperation for implementation.
