Legitimacy, ability to better govern the region and all it's people under one legal system.
It hit me when I looked at what flac called the measles map. It isn't just Palestinian violence that caused the erosion of a 2 state solution. I don't think Israel ever seriously intended for it to happen. The map starkly refutes it. Given that neither side, imo, is capable of honoring it.. what is left? The status quo?
Gaza can be a state eventually. But maybe WB should just be annexed.
Imo you cannot claim " legitimacy " by breaking the law. You cannot expect anyone to recognize as legitimate a crime against another just because they have been allowed to get away with it for decades.
If some people are only just now coming to the conclusion that Israel/Zionism never had any intention of honouring a two state soution, historical acceptance( Peel/UN partition ) was privately admitted as a stepping stone for the Jewish state by the likes of Ben Gurion and co , that shouldn't mean they should just capitulate to Israeli regional hegemony/propaganda and reject the rights of others.
If both sides are incapable of resolving it by themselves or with eachother there is always the option to put pressure on the US to stop it using its veto power in order to scupper the application of international law , in line with the decades long overwhelming international consensus and have the UN/ICJ sit both sides down an attempt a just resolution of the conflict based on international law instead of the status quo which is nothing but might is right.
I respect your willingness to offer a solution , I just think it lacks balance , justice and is a de facto encouragement for more international crimes being committed by states in the future , further undermining existing international law.
If people want to resolve the conflict to end the suffering they should use and support the application of international law which is the correct mechanism for setting out the framework and offering a more just resolution than the might is right alternative.
