German Institute for International and Security Affairs

In 1992, Perthes started to work at the German Institute for International and Security Affairs (German acronym: SWP). The main task of the SWP is to advise the German parliament and the Federal Government of Germany on questions of foreign and security policy, based on the institute's practice-oriented research.^[4] Until April 2005, Perthes was Head for the research group on the Middle East and Africa, and in October 2005, he became Director and Chief Executive Officer of the institute. After he left for positions with the United Nations, he continues with SWP as non-resident Senior Fellow.^[5] At the same time, he also taught as adjunct professor at the Humboldt University and at the Free University of Berlin. Based on his research, Perthes has published several non-fiction books as well as academic and policy papers on Syria, Lebanon, Iran, the European Union and the Palestinian Authority, including the wider Middle East. Apart from his native German, he is fluent in English and Arabic.^[6]

In September 2015, Perthes joined the Special Envoy of the Secretary-General for Syria, Staffan de Mistura, as Assistant Secretary-General and Senior Advisor to the UN in their talks for a peace process in Syria, and in October 2016, he became Chairperson of the International Syria Support Group's Ceasefire Taskforce for Syria.

In November 2015, Federal Minister for Economic Affairs and Energy Sigmar Gabriel appointed Perthes to the government's advisory board on the Transatlantic Trade and Investment Partnership (TTIP).^[7]

Special Representative for Sudan and Head of UNITAMS

On January 8, 2021, Perthes was appointed by the UN Secretary-General as Special Representative (SRSG) for Sudan and Head of the new UN Integrated Transition Assistance Mission in Sudan (UNITAMS).^[6] Following the 2021 Sudan coup d'état, Perthes held mediation talks with generals Abdel Fattah al Burhan and Mohamed Hamdan Dagalo, as well as with Prime Minister Abdalla Hamdouk, who was under house arrest,^[8] in order to "return to a comprehensive and urgent dialogue to restore partnership on the basis of the Constitutional Document and the Juba Peace Agreement."^[9]

On December 11, 2021, Perthes briefed the UN Security Council on the situation in Sudan after Hamdok had been reinstated on 21 November 2021 as Prime Minister. In his report and analysis, he made the following remarks:^[10]

Sudan’s military and political leaders will primarily have to rebuild trust with their own domestic public, particularly with the young generation. Immediate confidence-building measures and a visible commitment to bring the country back on a democratic transition path will be key. Similarly, Sudanese authorities will need to take demonstrable steps to regain financial, economic, and political support from the international community.

A day after the outbreak of violence in 2023, representatives from the Sudanese Armed Forces and the Rapid Support Forces agreed to a proposal by the United Nations to pause fighting between 16:00 and 19:00 local time (CAT).^[11] However, gunfire and explosives were still heard during the ceasefire, drawing condemnation from Perthes.^[12] Perthes briefed the UN Security Council on the situation on April 17, 2023.

Owing to the continuing fighting in Khartoum and other cities, the UNITAMS mission headed by Perthes relocated to Port Sudan to continue their mission in a safer environment. In June 2023, the military government of Sudan declared Perthes, who was on a mission outside of the country, no longer welcome in the country, accusing him of having encouraged the Rapid Support Forces to take up arms against the Sudanese army. In response, the office of UN Secretary-General António Guterres declared their full confidence in Perthes and refuted the action as incompatible with Sudan's UN obligations.^[13] After initially attempting to carry out his duties from abroad, Perthes submitted his resignation on September 13, 2023. Given the continuing military conflict in Sudan, he considered it impossible to carry out his work effectively from outside. At the same time, he warned of the danger that the fighting in Sudan could escalate into a “full-scale civil war.” In his last briefing to the UN Security Council, Perthes said:^[14]

Often indiscriminate aerial bombing is conducted by those who have an air force, which is the SAF. Most of the sexual violence, lootings and killings happen in areas controlled by the RSF and are conducted or tolerated by the RSF and their allies.

In October 2023, the UN Secretary-General appointed Perthes as the Head of the Independent Strategic Review for the United Nations Assistance Mission for Iraq (UNAMI), mandated by Security Council resolution 2682 (2023).^[15]
