The issues are; borders land swaps, jerusalem, refugees, recognition of israel as a jewish state, water, security, demilitirization. Does ANYONE think that the pals will recognize israel officialy as a Jewish state? not likely.... What about refugees? Will the pals accept that they cannot return? not likely. All other issues are sticky but can be worked out. So then; what will the palestinians demand to have all parameters set out in advance of talks achieve? NOTHING and they know it. They want to be seen to be reasonable, and then, when the parameters are declared unfair, they will STILL go to the UN, which as everyone knows, is entirely unbiased and balanced towards israel.....NOT....
