Do you have a good example of the UN helping to stabilize things?
Not really, just mentioning options that one might consider.
It did seem very useful and economical that when the US went into Bosnia, that UN and traditional allies were involved on our side, helping out to SOME degree, and that this might be compared/contrasted with this more recent episode in Iraq, a much more individualistic and cowboyish adventure.
There are LOTS of example of the UN sticking a finger in a dike but ignoring the water flowing over the top... there are LOTS of examples of "peacekeepers" being nearly as much trouble as the "bad people" themselves... there are actually precious few examples of UN "success" when it comes to using paramilitary power to "stabilize."
Good points which also need to be considered, yes.
I'm just saying that the UN is hardly a panacea for Iraq's problems - they have a longer track record of failures and actually aggravating situations.
Just something to consider.

Agreed. I try to be pretty equal opportunity when it comes to 'things to consider' and I try to find them on various sides of issues, for the sake of engaging critical discussion and potentially illuminating issues and potential solutions.
I don't have much interest in advocating particular solutions in too much detail, myself.
