Project Description

The UN has been activated in the management and resolution of armed conflict since the end of the Cold War. UN actions since 1946 are continuously analyzed. 

This project has studied the decisions in the Security Council in a series of publications.

The project also has an ongoing interest in UN Secretary General Dag Hammarskjöld and his performance in international conflict prevention.

This work relates to other Department projects on mediation, conflict prevention, UCDP, and to the work of targeted sanctions, see SPITS

Other Project Activities

In conjunction with the annual Dag Hammarskjöld Lectures  as well as the UN Day, the project has focused in presentations on issues such as the role of the UN Secretary General, UN uses of peacekeeping and UN arms embargoes.

Also, the project has been involved in reflections on the standing and reform of the United Nations security approach and organization.

It has also taken up the issue of the UN and regional organizations.
