Sako was shown photographs of projects already underway in Iraq, and graphics illustrating the reach of the aid efforts, Green said.
He emphasized that he did not think there was major disagreement between Sako and himself, but that it is "a matter of helping to show him what it is that we're doing and learn about more that we could be doing."
Green travelled to northern Iraq this past summer, together with Congressman Jeff Fortenberry and Ambassador-at-Large for International Religious Freedom Sam Brownback, to evaluate how U.S. aid money is being applied and see at first-hand the situation facing Iraqi minorities.
Following that trip, Green said, USAID had stationed a special representative, Max Primorac, in the U.S. Consulate General in Erbil as an on-the-ground special representative for minority assistance.

This new post, Green said, is to "take a clear-eyed, tough-minded look" at what is happening, to see what is working and what is not, and to help ensure results.
"I think what this whole effort is doing... is not only helping to meet some immediate needs, not only helping to do some strengthening and bolstering of infrastructure, but also hopefully strengthening the capacity of organizations on the ground for the long run."
The hope, Green said, is to "continue to build up this part of Iraq, so that families say, 'my future is here, I can live here, my children can go to school here, there will be the kinds of jobs that keep them here.'"
