3/ I won't be more 'explicit' about successive - you mean subsequent?- offers, none of them were deemed acceptable in any way, so here we are.
Were there, from Palestinians’ point of view, reasons to see them as being unacceptable? No right of return for Palestinians? Increasing numbers of illegal settlements on Palestinian land and no real Palestinian state offered?

Feb 2020 Peace Negotiations
^The Secretary-General of the League of Arab States said the measures proposed in the United States peace plan will impact many issues that should be addressed through negotiations, adding that the measures benefit only the Israeli side.
Whereas the “blueprint” was presented as the “fruit” of negotiations, it excludes the Palestinians and seems to imply that the plan will be imposed upon them. The plan appears to have been drafted with the idea of seeing it rejected by Palestine and the world, he said, adding that it also sets new parameters — granting land, settlements and Jerusalem to Israel, while not proposing a realistic two-State solution.
Instead, it seems to propose the creation of a single State with two categories of citizens: those with and those without rights, he noted.

I just went on to look up more about the @plan for Palestinians in 2020 and don’t see how they could have accepted it. It was a Trump and Netanyahu deal for a false state basically controlled by Israel and included lot more annexation for Israel.
