Oh my. Tell me you don’t know much about the conflict and its history without telling me you don’t know much about it.
What you’re spouting is student-level politics.
This situation is way more complex than that. It’s not the Omnicause version of ‘Palestinians = oppressed good guys, Israelis = bad guy oppressors’ that you’ve been sold. I would seriously suggest you do some reading into the background to the conflict (and no, 1948 or Balfour are NOT the start of it - it goes back centuries if not millennia prior to that).
A both sides situation is EXACTLY what it is.
Solving it will require BOTH sides to to come to see each other as fellow humans, and to come to the table prepared to compromise in the pursuit of peace, which will need to be given higher priority than who’s done what to who or who is right or wrong. Israel will need to cede territory. Palestinians will need to accept Israel should have some territory (turning down an offer for the majority of the land, over and above what would be proportionate for the size of the population, just because they didn’t want Jews to have any land at all was a massive own goal, wasn’t it).
The fact that much of the Middle East hate Israel, are hostile to it and its people, and actively support terrorism and other efforts to destabilise it, is a massive fly in the ointment, of course.
