The aftermath of the invasion of Iraq set unprecedented challenges to the United Nations in the political and in the human rights spheres.

The article looks at this trajectory from the angle of the involvement of the Security Council, the legal context, the protection of human rights and the striving for reconciliation, sovereignty and inclusiveness.
