Kurdistan for many years, including during the time I served there, between 2010 and 2013, was a place of refuge for thousands and thousands of Iraqis who felt they needed a haven. That's only been augmented by the recent crisis.
I don't know that I would characterize one community as being happier than another. My experience has been that the KRG, the Kurdistan Regional Government, has been most welcoming and most tolerant of all communities and has offered support above and beyond what even they were capable of providing. That is why people have chosen to flee there. They know it is a place where the threat is reduced.
My colleague will speak to the ways we have been assisting these communities.
Leslie.
