Israel will never willingly give up the land they stole, the core of Zionist ideology is settler colonialism. The high court and the mainstream opposition parties made it clear that they are neither willing to let Jewish people coexist with Palestinians as equals nor dismantle the oppressive Zionist state.
It is very short-sighted of you to claim that the only way to return land to their rightful owners is by voting for people who explicitly don’t want to do that.
That’s a shame.
