Darfur Refugees on the Kibbutz

Lisa Goldman posts about an interview with Darfur refugees who have found sanctuary at Kibbutz Maagan Michael. I'm surprised Israel treats refugees from "enemy countries" so harshly. Wouldn't people who flee from those governments to Israel make natural potential friends in the Arab world? Also, is someone from Sudan really more likely to be a terrorist than, say, a Palestinian living in friendly neighboring Jordan?
