The intangible, highly-sensitive questions of rights, dignity, responsibility and recognition are key to the refugee issue and central to how Israelis and Palestinians view themselves and the other. Both sides see these issues as zero-sum, and powerful social and psychological forces make flexibility difficult. Indeed, mistrust is so profound that even meaningful attempts at compromise will likely be perceived as insufficient, insincere — even insulting. Both sides fear that compromise on intangible issues could have severe implications for more concrete concerns.
