If and when the Palestinian Authority (PA) collapses, Jordan will bear the greatest brunt of the resulting humanitarian crisis. Such a collapse could be triggered by several factors, but will almost certainly lead to a mass exodus of Palestinians from Areas A and B. While Israel will probably opt for a minimalist containment approach, the government in Amman will have to choose: it can either come to the aid of the Palestinians in the territories, or it can allow them to enter Jordan for help. Israel and Jordan are both likely to favor the first option, which may then facilitate a solution to the problem of governance in the territories.
