I would just briefly add that I agree with everything Dr. Goetz has just said except that I would introduce a distinction between penalties for sexual exploitation and abuse, which I think can be imposed without undercutting the supply, as it were, of peacekeepers. However, on the question you specifically raised, about penalties for countries that cannot supply contingents with significant proportions of women, I think that would be a much harder penalty to impose, because it's really a seller's market in the current environment.
I would argue it's probably going to become more of a seller's market if the trend towards more robust peacekeeping continues. In other words, if peacekeepers are going to increasingly be put in harm's way, it becomes more difficult to penalize those who don't produce a contingent of the sort we might all like to see.
On the question of sexual exploitation and abuse, that is definitely something that the international community should press hard for penalties on.
