The one state agenda is going nowhere. People who advocate it are not looking at an important reality. One side rejects it and will always reject it and they have more power. And the international community supports a two state solution. So anyone other than clueless college students (there will always be some) who advocate the one state agenda need to get off that a viable solution. It isn't.
Most people know what compromises will be needed for peace but the current leaders dare not try to push for those compromises.
Basic outline is the Clinton Parameters. - 1967 lines with swaps, Jers split - Israel gets where Jews live, Palestinians get East Jers where Palestinians live, no right of return beyond a symbolic right of some older Palestinians to reunite with their families to live out their remaining years. Water right is an issue but that can easily be solved. What Olmert proposed was pretty close to what a settlement would look like.
