@UKBengali is right: If Israel wanted a One State solution then would have offered that a long time ago. But they never did because they know the demographic threat. Also, IF/WHEN the Palestinians let go of the idea of 'Palestine' then it would be the end of 'Palestine' because that would be an official acceptance. No people/nation accept that. Would the Muslims of the British era India accept to be part of a 'free and democratic' India with Hindu dominance? No, they wouldn't and they didn't and in contrast to them, the 'Palestine' is a highly emotive, long burning historic issue with a global importance.
PS. What's happening in Syria has huge implications for the entire Resistance front. I don't see Israelis shedding tears over Assad losing ground like in Aleppo.
