Iran & Iraq

So the US meet with representatives from Iran in Baghdad to talk about how each would approach Iraq. Seems to me that the US and Iran just need to take a low profile and let the Iraqis work out their future. Until basic services; electricity, water, and garbage removal are in place how can they even begin to work on feeling safe. The whole country is full of war weary people who have dealt with war since Iraq and Iran went to war.
