Exchanging territory for peace has not always provided the basis for Israeli-Syrian peace negotiations. In fact, for more than two decades Syria has demanded Israeli withdrawal from the Golan Heights without offering peace in return, and Israel has sought full peace with Syria without ceding the entire Golan. Both parties have accepted the principle for exchanging territory for peace based on UN Resolution 242, but how much territory for what kind of peace remains at an impasse. Since Israel captured the Golan in 1967, both Labor and Likud-led governments have defined the Golan as strategically critical to Israeli defense.
