I can add to this as well.
We have probably about 1.5 million refugees internally displaced in Syria, despite the end of the war. I have been to the Turkish border and I have seen thousands of tents. The people have been living there for 10 or 13 years. I imagine a lot of them were born there. The child doesn't know anything apart from a tent.
When I asked some of the people and leaders in these kinds of camps, they told me that they needed three things. They need to rebuild their houses and the villages. They need trusted health care. They need education. Nobody's going to go back to their villages to build a house if there is no health care and no education.
That's an excellent question. If we can help by building the education and health care in these villages and towns—not just building their towns, bridges and so forth—then a lot of them will come back to their villages.
