Again, your question is very important, and I wish there were a simple answer to it.
You will have seen that the largest troop-contributing nations tend to be militaries that don't have the same disciplined command and control structure. They may not be as well equipped even to go in the field. They are, in some ways, probably more at risk and coming from societies that might be strongly patriarchal. Add to that a conflict situation where women are vulnerable and may be lacking food and shelter. It takes a certain moral fortitude, both in command and control. However, imagine those young people we are putting, on both of sides of this line, into mortal danger, frankly.
All that is to say that it's a vexing issue. As my colleague Bruce said, it's not appropriate for the ICC. However, as he suggested, we can provide that training and that discipline to other countries to make sure these changes happen. They will happen over time.
