Just following up on this, the question of jurisdiction has plagued peace support operations on this, given that the discipline or punishment of members is the responsibility of the troop-contributing country. That's why one of the suggestions coming from outside the UN is to establish an arm's-length body that would investigate this. We know it's often very difficult for an institution to police and investigate itself.
If we had a referral mechanism that was outside of the UN and that could look at this and come up with recommendations, it would still not totally deal with the issue of holding individual perpetrators responsible, but it might help to establish new norms and new ways of working and bringing light to some of these concerns.
