The Mighty Heart star--who is touring Iraq in her role as a United Nations goodwill ambassador--insists more needs to be done to provide long-term solutions for the millions of displaced Iraqis.
The 32-year-old says, "There's lots of goodwill and lots of discussion, but there seems to be just a lot of talk at the moment.
"What happens in Iraq in the years to come is going to affect the entire Middle East. And a big part of what it's going to affect, how it settles, is how these people are returned and settled into their homes, brought back together and whether they can live together and what their communities look like.
"It's in our best interest to address a humanitarian crisis on this scale because displacement can lead to a lot of instability and aggression."
During her visit, Jolie also met with U.S. commander General David Petraeus and Iraqi Prime Minister Nouri al-Maliki.
