Both sides know exactly what the other side requires in order to have a deal. The Syrians insist on getting back their land and Israel insists on security arrangement. This was the situation already in 1999 when Barak dealt with Syria (thru Clinton). By now, both Syria and Israel have stated that they agree to talks without pre-conditions. This does not mean that the side are not aware of what would be a deal-breaker. In reference to Israel, it cannot demand that Syria will terminate its relationship with Hizballah ahead of the talks. They cannot "disarm" themselves ahead of talks. What usually happens during talks is that the sides agree to "cooling" the fires while talks last. For example, Israel can demand no arms transfer to Hizballah during the talks. Eventually, if the talks succeed, the deal will be as with Egypt: No support to anybody fighting Israel, no support in any way.
