Israel won’t stop until Palestine is gone. That’s been the plan the whole time. Israel never wanted peace or a two-state solution, they just wanted the land at all costs - including hypocritically committing genocide by erasing a country and many of its inhabitants.
Israel’s never honored any established boundary and takes every opportunity to further expand outside of their territory. Saying Palestine needs to negotiate with the Israeli government is the same as saying “Palestine needs to give up and not exist.” Hamas’s violent behavior and views have a lot to do with how the Palestinians have been treated over the decades and waving away Israel’s behavior that led to this is so short-sighted.
