In the aftermath of the attacks of September 11, 2001, the United Nations Security Council moved swiftly and laid the keystone of an international framework of counterterrorism efforts. Twenty years later, it’s past time to rethink all of them.
Back then, the Security Council obliged states to deny terrorists safe haven and material support through Resolution 1373. The resolution is still unique in its scope, with no limits on its application in terms of groups, geography, or time. To help advance it, Security Council members established the Counter-Terrorism Directorate, or CTED. They have visited over 100 countries to assess compliance and needs, and identified gaps and challenges in their counterterrorism frameworks.
