Another example, if I may say, is Sierra Leone, just next door to Côte d'Ivoire, with the same circumstances. There was a UN mission. It failed or was failing. They were backed up by the British. The British stabilized the area, along with, unfortunately, some mercenaries, but that's another story. Then the UN came in, this time with 19,000 troops, after the situation had been stabilized, and now that country has transitioned and gone through a couple of elections.
There are a few examples of where UN missions have been successful, largely because they're properly resourced from top to bottom.
