The Institute for Security Studies (ISS) published on 14 August 2018 a commentary titled "Sanctions Prove Key to Ending South Sudan's Civil War" by Meressa K. Dessu and Selam Tadesse, both at ISS.
The authors argue that UN sanctions at least put pressure on the conflicting parties in South Sudan to accept the peace initiatives proposed by the IGAD mediators. Success now depends on effective and consistent enforcement of the agreements.
