They're just so valuable that Israel isn't willing to let them go, that and the amazing heroic efforts of the Israeli defenders.
Isn't occupiers the correct word there Vlad ?
It is after all not Israeli land , and they were the ones who attacked , plus they had been shelling the heights for 3 years previously , initially targetting construction workers if my memory serves me correctly .

Anyhow Israel is willing to let them go , if there is a viable deal over the water , though in truth Syria will try to tie a water deal with Israel into getting its own water deal from Turkey which Turkey is unlikely to agree to .
