Majority on either side is not interested in a lasting peace that majority on the other side would be ready to accept.

Palestinians are ready to give up far more than Israel, but this is still not enough for the majority on the Israeli side, which Israeli elections clearly show.

There simply isn't a majority on the Israeli side which would accept pre-1967 lines with few land swaps, which is basically the minimum for a viable Palestinian state.

In the current negotiations Israel demands that it would be allowed to annex Jordan Valley or at least control it for 25 more years. According to World Bank, Jordan Valley could produce 3.5 billion dollars a year for Palestinian state (currently Israel gets 620 million dollars a year from the illegal agricultural colonies in there), which is twice the whole international yearly aid to Palestinians.
