It's not hard to see why Mitchell would draw hope from the analogy. By the time then-President Bill Clinton appointed him as an envoy in 1994, the Catholic "loyalists" and Protestant "unionists" had spent decades killing and maiming each other, as well as innocent civilians on both sides. Their fight was not over land, as in the Middle East, but over the status of their country: The Catholics wanted to join largely Catholic Ireland, while the Protestants wanted to remain within the United Kingdom. But as in the Middle East, religious differences had deeply envenomed a struggle over conflicting national aspirations. As Mitchell writes in Making Peace, his account of his role in the process, "Centuries of conflict have generated hatreds that make it virtually impossible for the two communities to trust each another.... Each assumes the worst about the other." As Nancy Soderberg, then Clinton's deputy national security advisor, puts it, Mitchell "forced them to see that there was a win-win side to moving forward, that it didn't have to be a zero-sum game." Mitchell's gifts for getting adversaries to see reason are "directly transferable" to the Middle East, Soderberg told me.
