Peace Policy: Solutions to Violent Conflict, September 2021

**Global Counterterrorism Efforts 20 Years after 9/11**: The bitter irony of the Taliban taking control of Afghanistan on the eve of the 20th anniversary of the 9/11 attacks makes a re-evaluation of U.S. and global counterterrorism policy more urgent than ever. This issue of Peace Policy offers perspectives toward that end with essays by Alistair Millar and David Cortright on guidelines for more effective multilateral cooperation against global terrorism, by Lisa Schirch on peacebuilding principles for preventing violent extremism, and by Naureen Chowdhury Fink on the benefits and challenges of incorporating gender perspectives.
