Powell is a peacenik, but that's kind of besides the point. They will save Arafat again because they don't know what else to do. The State Department is institutionally incapable of changing position or methods.
They will revert back to peace at all costs, because that is their "religion." To diplomats, war is failure.
Arafat should have been dead and mouldering by now. Instead he, and his sugar daddies in the Arab world are giving us the finger every day and watching, laughing while drop trow in for peace at all costs. There are times when war is the right policy. Powell is incapable of seeing that.
