We should start to work towards the effectiveness of our fight against sexual violence by making full use of the existing tools — for instance, by ensuring the deployment in relevant peacekeeping operations of women's protection advisers, who will strengthen the prevention and the response to sexual violence. Many challenges have delayed the deployment of those advisers, even when specifically requested by the Council. That should not be acceptable. Constraints in the establishment of peacekeeping missions should not be at the expense of women's protection advisers, especially if sexual violence has been identified as a major concern in a conflict or post-conflict situation.
