DougR, the UN can only do what the member nations allow it to do. So my answer was very much on point. The US is one of the most obstructionist of the member nations in the UN, using its veto power in ways that cripple the UN's ability to do what is needed. I find myself wondering what would happen if none of the UN member nations had veto power. I don't know enough about the ramifications of such a change to really have a solid opinion on it, but I do wonder about it.

As far as specific strategies to force compliance, it would seem to me that each situation would necessitate a different approach. I seriously doubt that there can be a "one size fits all" approach to enforcing resolutions.
