Why is it you feel it needs an actual destination?
Honestly there is no good solution unless it it forces down on BOTH Israeli and Palestinian from a position of power and influence, that would also enforce its mandate with a firm, fair and friendly manner, yet also be able to flip the switch and be utterly savage in draconian enforcement when it needed to be.
Short of that we will need to let them kill themselves until both sides are sick and want to talk.
The best we as Westerners can do is ensure that Israeli reactions are taken with proportionality, and that Iran and other nations that would like the see Israel wiped out, aren’t able to extent any influence in the area.
Keep in mind that for years, no one wanted the Jews, and Israel was set up primarily due to Western Guilt after WW2, and had their own dirty war prior to the formation.
While I am on Israeli’s side mostly in this area, I’m not blind to see that they have a lot of skeletons too, and until their Government follows their own and international laws WRT settlements, that Hamas et al. will constrantly be able to recruit support and have some victim card to play. The moral high ground must be occupied by actions, just not words.
Or if the Israeli’s decide for a lasting victory that they must bury the Palestinian hearts and minds, and accept being an international pariah, then I’m at a loss, as we as a collective society are failing stopping Russian from doing that in Ukraine, and unlike Israel, Russia has no legitimate claims that their actions are defensive at all.
