arabs are a minority in israel , they make up 20% of israel's population. for them to have any seats in the Knesset, enough to be the third largest party in the country is huge .
yes, they are represented in the knesset even less than they are in the general population, even with the big tent joint list party
you're right that palestinians and israeli arabs won't always have the same opinions on every issue but that's every party. what matters are the core issues , the main one being peaceful resolution and better rights for the palestinians.
no israeli political party with a chance of gaining power is offering this though.
to claim it'll never get better as long as israel exists is quite dire, as israel will probably never go anywhere and it would require only extreme force from powerful military to oust them. a highly developed nation of over 8million people isn't just going to disappear. and how would you morally be able to do something like that without genocidal crimes against humanity ?? then the fact that israel has nukes, yea not a good situation for anyone.at this point we need a government in israel that's willing to work with palestinians to a peaceful resolution not some war mongering piece of shit like netanyahu.
no one's saying you forcefully evict all jews from palestine, that's not realistic. it would be enough to replace israel with a democratic state founded on equality for all religions and ethnicities, with certain policies put into place to disempower the jewish power structure
an israeli government, that is, a government of the jewish state, working with palestinians for peace in good faith is not a realistic possibility, their interests are opposed. the best we can hope for is an arrangement where israel and the palestinian elites and power brokers come to an arrangement that keeps israel in a position of power over the palestinians but gives local elites some nominal degree of autonomy, prestige and economic well being
