I'm going to shift to Professor Welsh.
Professor, you mentioned something very interesting a little while ago in one of your answers, and that was about a military staff command at the UN. If we take the example of Bosnia in the early part of the nineties, where the UN had its role at the beginning and NATO had its role at the end, could you compare and contrast some of that, and maybe add a comment on where you think a military staff command at the UN would have been useful?
